Starbucks Interactive Storefront from The Media Merchants on Vimeo.
Here’s a nice piece of video (I like the stop-motion that shows the install process) of a Tazo Tea promotion done at a pair of high profile Starbucks locations in Vancouver and Toronto. These are window projections with a touch foil overlay, by the looks of how the interactive is done.
The promotion was executed by Toronto-based Media Merchants.
