Share Happy - Smile Activated Vending Machine wins Best Kiosk/Installation at SXSW - Love this

Description from the Wall's/Unilever site:

"Share Happy

First we helped Walls create their new global brand positioning: "Share Happy".

Then we needed to bring Share Happy to life in simple, fun way with ice cream at the heart.

We created a wide range of activation but the centrepiece is the world's first smile activated vending machine.

Simply smile at our vending machine and it gives you a free ice cream.

Share Happy!"
