That's a pretty good camera, I could barely tell it was a TV screen :D.

I could see how difficult it could be made on PS3 and with the sheer idea of making something like this, but you need to take into consideration that there are plug-ins such as world edit, which can generate hollow spheres or sphere dementions. 

Congrats on doing this on PS3 by the way, just keep that all in mind and try sticking to more detailed projects, I'm sure they'll be much more appreicated :D I'll sub for that!

It's.... not that complex. It's just two circles intertwined in the air.
