A Digital Pet That Sits on Your Can and Gets Drunker Every Time You Take a Sip
Matty Benedetto of Unnecessary Inventions built The Buzz Buddy, a miniature digital drinking companion that attaches to a can. Its sip-detection system registers each time the user drinks, making the on-screen character take a matching sip and gradually filling its Buzz Meter.
Over time the character evolves into progressively looser states. Tapping it makes the character dance, while swiping down displays usage statistics.

The problem is not wanting to drink alone, and the solution is not inviting another person but attaching a digital drinking companion to the can. Better yet, it changes along with you sip by sip.
