BLINKDRINK transforms your phone from “that thing you play with when no one is talking to you at the bar” into a pint-sized party. Open the app, choose your color, and put your drink on top. BLINKDRINK uses the prism of your poison to keep time to whatever song is playing. You’re thinking, “iPhone as coaster? Sounds like a bad idea.” Well we put a lot of drinks on top of phones while making this thing- the only bad ideas generally happened afterward. Source
