Starbucks has given the caffeinated crowd a new reason, other than the free WiFi, to stop by a couple of locations in Toronto and Vancouver -- interactive window displays! Taking sidewalk passers-by on a journey to assemble their favorite Tazo teas, the interactivity comes via a vinyl screen, projector, and gesture controls. We've already seen an interactive storefront in the US, so its about time our friends up north got some geekified advertising of their own. Vid's after the break.
