DeLighTable: Touch-Sensitive Glow Table
The "DeLighTable" started as an art project but can now be commissioned for your living room for only $2,300—a fair chunk of change for home furniture, perhaps, but not outlandish for a bar or other public area where a fully waterproof, touch-sensitive, light-reactive table might entice customers to buy more drinks to light up.
Born Rich has a video of the prototype in action. Looks fun, if simple.

I could make this using a vacuum sealer, some soy sauce, and a box with lights.
Booooooooooring.
