Chimoosoft Capture Me is a freeware Mac OS X utility for performing screen captures on a Mac. Yes, Cmd-Shift-3 (full screen capture) and Cmd-Shift-4 (selective screen capture) still works in Mac OS X Leopard. But, Capture Me provides a reasonably easy way to capture screen segments. It is also supposed to allow you to capture and create successive screens to create an animated screen capture. However, it wasn't apparent to me what to do after starting that capture mode and I didn't see any instructions on the web site for this feature.
