It's just a kooky, Surface-related R&D project for now, but Microsoft's SurfaceWare holds the promise of optimizing your time-to-alcohol consumption ratio. Combining software with a level-sensing tumbler, SurfaceWare effectively measures the amount of liquid remaining in your glass. The specialized drinking glasses are fitted with a prism that works in combination with Surface's infrared detecting camera to reflect light as the prism rises above the level of your emptying beverage. Surface will then alert bar staff of your need or automatically purchase another round at just the right time. You certainly don't want to be wasting time in Vegas waiting on your disco fuel. Video walkthrough after the break.
