WindowGrin
 Interactive entertainment for digital screens

Shop windows are boring. WindowGrin adds the missing fun! 


WindowGrin is an entertainment solution for retail, interactive shop windows and digital signages. 

WindowGrin is a magic mirror concept that mirrors the customer's face with a virtual character’s image, while he's standing in front of a live digital screen set up in your shop's window.  Our virtual characters will mimic the facial expressions of your customer. Our game experiences draw and keep your customer in front of your shop window.
