Computer Science Thesis Poll

[gwcahill]

Hi,
I am trying to come up with a solid master's thesis idea for my computer science degree. I have taken classes covering both games and computational geometry (as well as graphics and so on). Anyway, I am really interested in doing a thesis on graphics or gaming but I'm not really sure where to go with this.

I do have interests in path finding, collision detection, and animation....but please don't let this limit your suggestions.

Any ideas?

Thank you in advance!
