Québec City Magic Festival: The Magic Poster

Québec City Magic Festival: The Magic Poster

To promote the Québec City Magic Festival, lg2 makes the poster behave like a trick, not a billboard.

The creative is a magician’s hat poster with a message printed in invisible ink. Curious passers-by discover the mechanic by doing what people already do. They pull out a phone, take a picture, and turn the flash on. The flash reveals the hidden copy, and a lucky few are rewarded with a free ticket for the festival’s closing show.

A poster that turns curiosity into participation

The mechanism is invisible ink plus a flash-triggered reveal. Instead of asking for attention, the poster pays attention back. It gives you a reason to stop, and it gives you a satisfying “aha” the moment you do.

In high-traffic city out-of-home placements, the best interactive work rides on habits people already have, not instructions they have to learn.

In out-of-home, the strongest interactive ideas do not demand a new behavior. They attach to a behavior already in the environment and simply add a twist.

Why it lands for a magic festival

The medium is perfectly aligned with the message. The campaign does not merely advertise magic. It performs magic in the street. That alignment makes the experience feel like a preview of the festival rather than an ad for it. The real question is whether the medium can demonstrate the experience you are selling, not just describe it.

Extractable takeaway: When promoting an experience product, make the marketing behave like the product. Let the audience sample the feeling, not just read the promise.

The free-ticket twist strengthens the loop. The reveal provides instant reward. The prize provides delayed reward. Both motivate sharing, because people want friends to try it and to see if they win.

How to design a flash-reveal OOH interaction

  • Hide something worth revealing. The reveal must feel like a payoff, not a gimmick.
  • Use a native trigger. Flash photography is a default phone capability, not an app install.
  • Reward the behavior. Even a small chance of winning can meaningfully increase participation.
  • Make it repeatable. The interaction should be easy enough that people can show someone else on the spot.

A few fast answers before you act

What is “The Magic Poster” concept?

A festival poster printed with invisible ink that reveals its message when someone photographs it with a phone flash, turning a passive billboard into a small magic trick.

Why is the flash-triggered reveal effective?

It uses a built-in phone behavior, creates instant payoff, and turns the audience into the operator of the trick, which increases attention and sharing.

What makes it more than a novelty poster?

The mechanic reinforces the product truth. The campaign demonstrates magic rather than merely claiming it, making the ad itself a preview of the festival experience.

How can brands adapt this without copying the exact technique?

Design a simple reveal that matches your story, attach it to a native behavior in the environment, and ensure the revealed content is genuinely rewarding, not just hidden for hiding’s sake.

What should the hidden message say?

Keep the revealed copy short and emotionally rewarding in one glance, so the flash moment feels like a payoff and not a puzzle.

Theraflu: Thermoscanner

Theraflu: Thermoscanner

With the start of flu season, Theraflu in Poland wants to create a tool that lets passersby check if they have a fever without interrupting their daily commute.

So Saatchi & Saatchi develops what is billed as the world’s first outdoor ad with a live thermo-scanner camera, able to check the body temperature of the person standing next to it in real time.

The thermo-ad also lets people take a thermo-selfie, which here means a thermal-style image of themselves, download it via a microsite or QR code, and share it using the hashtag #TherafluThermoscanner, or send it by email to their boss as an explanation for absence.

Turning a symptom into an instant public check

The mechanism is a simple swap. Thermal cameras are usually associated with controlled environments like airports or clinics. Here, that same visual language is put into a familiar citylight so the “should I worry?” moment can happen on the street, in seconds. That shift matters because it turns a clinical signal into a low-friction commuter interaction, which is why the idea feels immediately useful instead of purely theatrical.

In European commuter cities, out-of-home works best when it adds utility without forcing people to break stride.

Why it lands

This works because it respects the reality of flu season behavior. Many people keep moving even when they feel off. The installation meets them where they already are, makes the result legible at a glance, and gives them an immediately shareable artifact that doubles as social proof and practical communication.

Extractable takeaway: If your message is health-related and time-sensitive, design a public utility that produces a clear personal output. Then make that output easy to reuse in the next real decision the person has to make.

What Theraflu is really buying

Beyond awareness, the ad builds a reason to act early. It reframes “flu medicine” from a product you remember later into a category you prepare for now, while the viewer is still in the mindset of assessing symptoms and deciding what to do next. The real question is how to make symptom checking feel immediate enough to trigger action before people default to pushing through the day. The stronger play here is utility-led brand framing, not spectacle for its own sake.

What to steal from the Thermoscanner

  • Embed the benefit inside the medium. If the media unit demonstrates the promise, the claim needs less persuasion.
  • Make the result portable. A shareable scan turns one interaction into many impressions.
  • Design for the commute. Fast, glanceable, and low-effort beats “immersive” when people are in motion.
  • Give sharing a job. Social posting is optional. Emailing a boss is a real utility hook.

A few fast answers before you act

What is the Theraflu Thermoscanner?

It is an interactive outdoor ad that uses a live thermal camera to estimate body temperature in real time and indicate whether a passerby may have a fever.

Why put a thermo-scanner in an outdoor ad?

It makes fever detection feel instant and accessible during daily routines, and it turns a brand message into a practical tool.

What is a thermo-selfie here?

It is a thermal-style image generated from the scan that people can download and share, or send as a message to explain they may be unwell.

What makes this more than a gimmick?

It is tied to a real, time-sensitive decision. “Do I have a fever?” and it delivers an output that can be reused immediately.

How can other brands apply the pattern?

Find a high-friction question people avoid answering, then build a quick public utility that returns a clear personal result and a shareable artifact.

Porsche: Interactive Hologram Print Ad

Porsche: Interactive Hologram Print Ad

To launch its latest 911, Porsche created a print ad that behaves like a device. Working with agency Cramer-Krasselt, Porsche placed a small acetate sheet into Fast Company’s April issue, turning a magazine spread into a build-it-yourself prism and an interactive “hologram” experience. In this context, “hologram” refers to a prism illusion created from tablet-screen content.

The execution ran as a four-page spread inserted into around 50,000 copies, complete with assembly directions. Porsche billed it as the world’s first interactive hologram print ad.

When a magazine page turns into a viewing tool

The mechanic is the whole point. You fold the acetate into a small prism, place it on top of a tablet, then use the screen content to create the floating 3D-style illusion inside the prism. Print does not “show” the car. Print enables the car to appear.

That shift matters. Instead of asking a reader to imagine innovation, the ad makes them assemble it, which turns curiosity into action.

In premium automotive marketing, making print behave like a device is a fast way to earn attention from audiences who think they have seen every format.

Why the prism matters more than the hologram

The hologram effect is a spectacle, but the prism is the message. It signals precision, engineering, and fascination through the act of building. It also gives the reader a reason to keep the insert, show someone else, and replay the experience, which is exactly what print needs when attention is scarce. The real question is whether the build step makes “innovation” feel earned rather than claimed.

Extractable takeaway: If you want a print unit to signal modernity, make it an enabling tool the viewer assembles, so the interaction itself becomes the proof.

What Porsche is really buying

The business intent is to make a high-end model launch feel as advanced as the product story. A conventional print page can carry features and beauty. This format carries a proof point. Porsche can credibly say, “We pushed the medium,” and that halo transfers to “we pushed the car.”

This is a smart launch move because it turns medium innovation into a product halo without adding more copy.

Steal this print-as-device pattern

  • Make the reader do one small action. Folding beats scanning when you want ritual, not convenience.
  • Let print enable the experience. The page becomes the trigger, not the canvas.
  • Keep the rules idiot-proof. If assembly fails, the entire idea fails.
  • Use scarcity and selectivity. A targeted drop can feel more premium than mass coverage.

A few fast answers before you act

What is an “interactive hologram print ad”?

It is a print ad that includes a physical component, in this case an acetate prism, that turns a tablet screen into a hologram-style viewing effect. The print unit is the enabling tool.

How does the prism create the hologram effect?

The prism reflects and refracts imagery from the screen into a floating illusion. The viewer sees the content “inside” the prism rather than flat on the tablet.

Why put this in a business magazine like Fast Company?

Because the audience expects innovation and is more likely to try a format experiment. It also gives the stunt credibility as “design and tech”, not just “advertising.”

What is the biggest execution risk?

Friction. If instructions are unclear, materials are flimsy, or setup takes too long, people drop the experience before the payoff.

What should you measure for a print-to-device activation?

Completion rate of the build, repeat views, sharing behavior, and brand recall lift versus a standard print placement. The real KPI is whether the mechanic gets retold accurately.
