Looking for stereoscopic content

I’m looking for stereoscopic (side by side or cross-eyed, -not- anaglyph or crystal eyes) real-time content of any sort. Could be games could be scientific visualizations, windows or linux. Just has to be interactive in real-time. I’m hacking some stuff right now, but I’m looking for ready-to-go content.

Anybody know a good place to find anything like this?
