"Smart" Beer Coasters Provide New Drinking Game Ideas!

I was intrigued by these new smart coasters for a variety of reasons--mainly they're cool to look at, and they provide a host of new drinking game opportunities. Another cool thing about these beer coasters is that you can build them yourself! Check out the video...

The idea for these new smart drink coasters was thought up by a company in Redwood City, CA called Sentilla. This company develops new and innovative "smart" designs. They recently thought up the design of these cool little gadgets with the idea that these new coasters would be able to sense when a drink is placed on them and whether or not the drink needs a refill.

Here are the basic characteristics of the smart coasters according to the Sentilla website:
  • The coasters know when a drink is placed on top of them and when it is removed.
  • The coasters notify each other when new things occur (a drink is placed on them, removed, etc)
  • The coasters provide "visual feedback" using lights embedded within them.
  • The coasters are wirelessly interconnected.
These new smart coasters open up a variety of new drinking game opportunities. One of these is based on the "old school" game called "Simon". This is a memory game where you have to remember the pattern of the lights. Imagine playing this while your drinking, and you can't remember anything! There are a ton of other drinking games that could be used with the smart coasters, but I don't have a huge imagination to dream them up. Post your ideas below.
