spectacle is a simple application for capturing desktop screenshots. It can capture images of the entire desktop, a single monitor, the currently active window, the window currently under the mouse, or a rectangular region of the screen. The images can then be annotated, printed, sent to other applications for manipulation, or quickly be saved as-is.
