Kloss DeLighTable

At first glance the Kloss DeLighTable might look like a regular, slim coffee table, but its touch-sensitive surface that glows in different colors as you move your hand across it tells you otherwise. It runs on a safe 12 V, its waterproof surface protects the electrical circuitry within from spilled drinks, and drink glasses are illuminated in a unique way.

You can even "write" on it.  These entertaining features – along with its price, $2,200 (or £1,200) – make it especially suitable for bars.

More information can be obtained from the Kloss website and a very "illuminating" video can be found here.
