The Swedish Post: The Sound of Green

The Swedish Post has a collection of pre-stamped parcels that makes it easy to send things. The task for ad agency Åkestam Holst was to tell people that it was possible to send almost anything overnight with these pre-stamped parcels.

So they packed 80 parcels with all sorts of stuff and recorded 80 specific sounds. Those sounds powered “The Sound of Green” competition. Users picked a parcel, listened closely, and guessed what was inside. If they got it right, the Swedish Post sent the same parcel to the winner the very same day.

After a reported 140,240 guesses, the competition finally came to an end.

When proof beats promise

The mechanism is a neat translation of capability into play. Instead of listing what you can ship, you create 80 mystery parcels, record what they sound like, and let the public test their attention. The prize is not a voucher or a discount. The prize is the actual thing, delivered fast, which quietly demonstrates the core promise.

In consumer postal markets where “overnight delivery” sounds like a commodity claim, capability stories land better when they are demonstrated through a simple, repeatable experience.

The real question is whether the brand can make overnight delivery felt before someone ever ships a parcel.

Why it lands

This works because it turns logistics into curiosity. Sound is intimate and surprisingly hard to fake, so the listener leans in. The guessing format also creates a low-friction reason to spend time with the brand, and the same-day fulfilment makes the payoff feel real, not promotional.

Extractable takeaway: If you are selling an invisible service, build a public game that forces the benefit to show up as evidence, not copy.

What service brands can borrow

Demonstrate the promise. Replace “we can do anything” with proof people can experience.
Use a constraint to create focus. 80 sounds is large enough to feel rich, small enough to feel curated.
Make the prize the product. Shipping the parcel is the cleanest way to validate shipping.
Design for repeat attempts. A guessing mechanic naturally invites “one more try”.

A few fast answers before you act

What is “The Sound of Green”?

An online competition by the Swedish Post and Åkestam Holst where people listen to recorded parcel sounds, guess the contents, and winners receive the same parcel delivered the same day.

What is the core mechanism?

Pack real parcels, record the sounds they make, then let users choose a parcel sound and submit a guess. Correct guesses trigger real fulfilment.

Why use sound instead of photos?

Sound forces attention. It is less immediately obvious than visuals, and it creates a stronger sense of discovery when you finally figure it out.

What does this teach about marketing service businesses?

Claims are easy to ignore. Demonstrations are harder to dismiss, especially when the demonstration is interactive and ends in real delivery.

How do you keep a contest like this from feeling gimmicky?

Make the payoff identical to the promise. In this case, the reward is the service itself, delivered fast.

Nutricia: Baby Connection

Young parents all over Belgium rely on Nutricia babyfoods every day. To support mums even before their baby is born, Duval Guillaume helped Nutricia create Baby Connection, an iPhone app designed to get dads more involved in the pregnancy.

Baby Connection works best when you use it as a couple. There is a mum version and a dad version, and everything each parent adds is automatically synced with their partner’s phone. The app can even transform two iPhones into one big screen.

A couples app that turns involvement into habit

The mechanism is simple and deliberate. Split the experience into two roles, then keep both roles in lockstep through syncing. Add a playful physical trick, two phones acting like one screen, to make “doing this together” feel tangible, not just promised.

In Belgian consumer brand building, support tools land best when they reduce friction for both parents and make the dad’s role practical, not symbolic.

Why it lands

This works because it shifts the conversation from “be more involved” to “here is exactly how”. Shared inputs, shared visibility, shared moments. The app design quietly nudges the couple into repeated check-ins, which is where involvement stops being intention and becomes routine.

Extractable takeaway: If you want two people to share responsibility, design the product so both can contribute in small ways, see each other’s contributions instantly, and feel like a team without extra coordination effort.

Launching an app with an experience, not a banner

The real question is how to make shared participation feel real before the baby arrives, not how to advertise another pregnancy app.

To launch Baby Connection, Duval Guillaume backed the app with a campaign designed to be as distinctive as the product itself, and to pull the idea into public conversation beyond the app store listing.

The stronger move is to market the shared behaviour the product enables, not just the app itself.

What pregnancy-support brands can borrow

Design for the couple, not the individual. Two roles, one shared narrative.
Make syncing the default. Shared visibility is the involvement mechanic.
Add one physical “together” moment. A simple device interaction can signal partnership better than copy.
Launch the product idea, not only the product. If the behaviour change is the point, market the behaviour.

A few fast answers before you act

What is Nutricia Baby Connection?

A paired iPhone app for expectant couples, with separate mum and dad versions that sync pregnancy updates and activities between both phones.

What is the core mechanism?

Two-role design plus automatic syncing, so both parents can add and see information without manual coordination.

Why does the “two iPhones as one screen” idea matter?

It turns a digital feature into a physical couple moment, reinforcing that pregnancy planning is shared, not solo.

What is the business intent behind this kind of app?

To support and deepen trust with parents before birth, by providing a practical tool that keeps the brand present in daily routines.

What is the most reusable lesson here?

If you want involvement from a second person, make contribution easy, feedback immediate, and shared progress visible.

Renault Espace: iPad 360° View

The Renault Espace is a large MPV from French car-maker Renault. With a new iPad app, Renault gives users an onboard view of the Espace like never before.

The application is a 360 degree interactive video. All you need to do is tilt your iPad and explore different angles as if you were right there.

A virtual showroom that behaves like your head

The mechanism is refreshingly direct. The app uses the iPad’s motion sensors to map physical movement to viewpoint changes inside the car. Instead of tapping through static photos, you “look around” by moving the device. It is a smart use of motion sensing because it keeps the interface invisible and the focus on the cabin.

In automotive consideration journeys, anything that increases spatial understanding of the interior helps bridge the gap between online browsing and a test drive.

Why it lands

Interior experience is one of the hardest things to communicate in standard car marketing. This solves that by letting the user control perspective. It also creates a calmer kind of interactivity. No menus, no instructions, no friction. Just tilt and explore.

Extractable takeaway: When your product has a strong spatial component, give people viewer control over perspective. It builds confidence faster than adding more copy.

What Renault is really trying to achieve

The real question is whether this kind of “tilt to explore” experience reduces uncertainty enough to make a showroom visit feel worth it.

This is a digital test-sit, a lightweight simulation of sitting in the cabin so you can judge layout and comfort before a showroom visit. It is designed to make the Espace feel accessible before a showroom visit, and to reduce uncertainty about cabin layout, visibility, and perceived comfort. Done well, it also keeps attention longer than a typical brochure flow.

Steal this for spatial product demos

Use motion as navigation. If the device supports it, motion control can feel more natural than UI controls.
Keep the interaction single-mode. One behaviour. Tilt to look. That simplicity is the feature.
Prioritise the interior. For family vehicles, cabin experience often sells more than exterior styling.
Let curiosity drive. Give users freedom to explore, rather than forcing a predetermined tour.
Make it fast to load. Interactive video dies when buffering becomes the dominant experience.

A few fast answers before you act

What is this Renault Espace iPad app in one sentence?

It is an iPad experience that uses a 360 degree interactive onboard video so users can tilt the device to explore the Espace interior from different angles.

Why use 360 video instead of a standard photo gallery?

Because it communicates space and layout more effectively. Users can look where they want, which reduces uncertainty faster than scrolling images.

What makes “tilt to explore” feel intuitive?

It mirrors how people look around in real life. Physical movement maps directly to viewpoint changes, so interaction feels natural.

What is the main execution risk?

Performance. If motion tracking feels laggy, or the video quality is poor, users will abandon quickly and the experience will feel like a gimmick.

What should you measure if you ship this type of experience?

Time spent, percentage of users who explore multiple viewpoints, completion rate, repeat sessions, and whether it correlates with test-drive requests or dealer inquiries.
