The other day I had a chance to look at the PS3’s UI, and I just couldn’t get over the slowly-moving, wavy shape in the background. So I figured I’d make it in XNA. I was pretty close on my guess about how it worked.

It just uses a constantly deforming plane and a pretty simple shader. The variation is just a lot of math modulated by position on the plane, time, and a random “seed” value. That way, while it has some coherency in its movements, it still has plenty of variation to make it interesting.

Try it out.
