Can anyone recommend me any free webcam software?

I've got one of those Xbox 360 webcams from a while a go that I'd like to use but it doesn't come with any software for my PC. I've looked for a program but I can't find any decent ones. I'm just trying to find some software I can use to take profile pictures and whatnot.

Thanks in advance
I fell asleep on my arm once, scariest thing that ever happened to me. I thought it was kill.
