A demo has already been available in Japan through PSN but today US gamers can start to tackle this weird and unique puzzler.

The demo is free to get hold of and has you optically manipulate a 3D world to help a little guy get across the levels.

If you've absolutely no idea what kind of puzzler could do such a thing then visit the PlayStation blog to see a clip of Echochrome in motion.

It really does look quite the brain teaser at times, if you've got a PS3 or PSP then don't miss out.
