The sign was built using an extremely water-repellent material called Monat from Japan’s Unitika. The fabric predictably beads water off its surface, resulting in a dramatic display of droplets coursing down its face. It’s best explained by watching this video the guys at DigInfo.TV shot:

The word “SENSEWARE” at the top of the display is formed using tiny beads of water which are secreted through pinholes in the fabric. When the beads reach just the right size, the droplets slide down the face of the slightly tilted fabric, then recirculates back to the top, and starting the show all over again. It’s pretty spectacular, especially when you realize that this entire show is basically done using a sheet of fabric, a water pump and some tubing to circulate the water.

The AquaRain is a battery-powered device that floats along the surface of your bathwater and sprays a geyser of constantly recirculating water into the air in a couple of different patterns. Add to that a set of three color-changing LEDs, and you’ve got yourself a serious light show in your tub.

While it might not come close to the fountains at the Bellagio in Las Vegas, it’s should offer enough of a display for most bathtubs. The AquaRain is available now from NCSX for $39.
