I'm not sure how much time you spend on the 'non-human' primates these days; we got quite a bit of content in that area when I was a student, but I do know that things have changed!
Anyway, lemurs (prosimians) are part of that group. And one that's always fascinated me is the aye-aye - that strange little beast with the very long thin finger (used in hooking stuff out of holes in trees). I don't think I'll ever see one in the wild, though, so I was delighted to find that the Duke Primate Centre in the US has some footage available. (There are links to more DPC videos through this one.)
