Some projects are inspired by a legitimate need, some are the result of moments when you say "wouldn't it be cool if...", and some lie in between. This idea began closer to the second option but as it's progressed, I've realized that perhaps it could be a useful item in the right context.
I started by thinking how cool it would be if there existed a coaster that lit up, changing colors as your drink level decreased. From a purely "what the heck" standpoint, it was a super neat idea that had to be pursued. As I began designing and building and talking to different folks about the idea, I realized that it actually could be great to have, for example, in restaurants, bars, night clubs, and the like as a great way for waiters to keep an eye on drink levels and keep the customers satisfied. If I ever own a nightclub
, I'll definitely make these a standard issue.
