For some folks, bath time accessories include a glass of red wine and a novel. Other dudes prefer "Song of the Whale" and a roach. But for those seeking a bath tub experience where a Pink Floyd laser show invades a Japanese arcade submerged in Las Vegas' Bellagio fountain, thankfully there is AquaTop.

Developed by Koike Laboratory researchers at Tokyo's University of Electro-Communications, AquaTop is an interactive entertainment system that turns bath time into an immersive experience of colored light, sound and, of course, water. All it took was a six months of coding, a Kinect camera, a projector and some waterproof speakers.
Users begin by mixing bath salts into the water, making it milky, which provides a better contrast as a projection surface. Images are then projected onto the cloudy water, which also reflects the infrared light of the depth-sensing Kinect that tracks finger movement. Whether held above the water, on the surface or poked from below the surface, hands and fingers can be used to interact with orbs of light, images and other shapes.
