I've got an internship working for a research group an area university-- implementing a system we use on the Nintendo DS (because it's a neat platform and it's portable) and it's turning out that the Nintendo DS might perform better than the full-scale system running on modern desktop machines

Sorry to be so vague; not sure how specific I can be about what I'm working on.
I applied for Microsoft... never heard anything back from them, though (I think I had a typo in my resume that I didn't detect until after I submitted it to MS... hit \ instead of backspace when I made a last-minute correction, .Net to .NET I think).
