Q-Games' three-dimensional music performance visualizer ... experience PixelJunk 4am, which we can neither describe nor play without some handwaving, will be released on May 15, the company announced today. The free Pixeljunk 4am Viewer, which allows you to watch others' 4am performances live, will also be out that day.

Before the official release, a beta will be distributed to some PlayStation Plus members on May 1. During this time, Q will host special live performances including one by DJ and 4am producer Baiyon.

Even if you're not a Move owner or musician, there's a feature that may appeal to you. In the PlayStation Blog post announcing the release date, lead designer Rowan Parker announced that "PixelJunk 4am can be used as a stand-alone music visualizer to play your favorite music from your PS3." Five visualizers will be available right away, and you can unlock more by playing the game.
