Let's Tap is useful as more than just an application for testing the "tapping potential" for boxes and other nearby surfaces, it can also be used as a music visualizer (and as the minigame collection it was intended to be, of course)!

The Wii title includes a visualizer mode with five different options -- Fireworks, Paint, River, Ink (above), and Gem Game. As with the other modes, you lay the Wii Remote down on a flat surface and tap your fingers nearby to interact with the visualizers.

For this demonstration, SquidTV placed his Wii Remote on a box sitting on top of a speaker playing Pink Floyd's "Wish You Were Here". The visualizer takes a while to register the song, but before long, David Gilmour's voice swoops in to draw fish and stingrays onto the screen.
