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.

WhatsApp Taxi

You need a taxi. Instead of calling or using a dedicated app, you open WhatsApp, share your location, and place the order by message. Taxi Deutschland positions “WhatsApp Taxi” as a simple way to request a cab in major German cities using the behavior people already know. Messaging.

Why this shows up now

After years of public sharing and transparency on social media, people gravitate toward more intimate, private, and even anonymous ways to communicate. That shift boosts the popularity of messaging apps and ephemeral messaging. Chat apps become hubs for social networks, games, e-commerce, and more.

The service. Taxi ordering by location message

Taxi Deutschland launches a new service called “WhatsApp Taxi” that allows users in major German cities to order a taxi by simply sharing their location via a WhatsApp message. The interaction is reduced to one core input. Your location.

The pattern. Messaging becomes an interface

Just last week I wrote about how KLM was starting to use Facebook Messenger for customer service related queries and tasks. WhatsApp Taxi sits in the same movement. Utility shifts into the messaging layer, which means the chat app becomes the place where the service starts, is confirmed, and is updated. The chat thread becomes the service surface.

In service categories where the audience already coordinates through chat, the smarter move is often to reduce entry friction rather than build another interface.

Why this lands for service adoption

This is a stronger service design move than another branded utility app because one familiar message and one high-confidence input make the service easier to try, which is why the interaction feels lighter and more repeatable.

Extractable takeaway: When the job to be done can be triggered with one trusted input inside a familiar chat flow, messaging can outperform a dedicated interface on adoption because it removes setup and learning cost.

The real question is whether your service needs a dedicated interface at all when messaging can already handle the request, confirmation, and follow-up. For Taxi Deutschland, the business intent is to reduce ordering friction and capture demand inside an existing behavior instead of forcing a new app habit.

What service brands can lift from WhatsApp Taxi

Ship in the behaviour people already have: If your audience already lives in messaging, put the service where the habit already exists.
Reduce the request to one high-confidence input: Location-first is a clean pattern when the service is fundamentally “come to me”.
Make chat the interface: Treat the thread as the order surface. Request, confirmation, updates, and support stay in one place.
Keep the interaction minimal: If one message can start the service, adoption is easier than “install app, register, learn UI”.
Design for repeat use: The same simple flow should work the second time without needing new learning or setup.

A few fast answers before you act

What is WhatsApp Taxi?

Where does it work?

Taxi Deutschland positions the service for use in major German cities.

What is the core user action?

Send your location via WhatsApp message to initiate the taxi order.

Why is this a marketing and product signal?

It shows how messaging apps evolve from communication tools into utility layers where services can be initiated and managed.

What is the transferable lesson for brands?

If your service can be reduced to a small set of high-confidence inputs, messaging can become a low-friction interface that people already understand.

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.
