Capture Me is a flexible screen capture and recording utility for Mac OS X which features a floating capture window, several saving options, and resize ability.
To use the program, drag and resize the floating window to cover the area you want to capture. Then click in the window to capture the screenshot. You can resize it, copy it to the clipboard, and save it in a variety of formats and locations. Its behavior is customizable with respect to what happens after a capture. A newly added movie recording mode now allows up to a one minute long QuickTime movie (no sound) to be produced.
