Constrictor is a screenshot utility for OS X. Constrictor lets you position a frame and then snap the area inside, applying border effects and saving in a variety of formats. It's even scriptable.
The frame is transparent, so you can see the desktop and the icon through it. The lumps on the sides and corners are knobs you can use to resize the frame.
Mouse clicks go right through the interior of the frame, so the frame really just delineates an area of your workspace without interfering with your work in other applications.
Once you've got your frame positioned where you want it, you can take as many snapshots as you want to of that area, with a variety of options for the snap's appearance.
For example, you can scale your snapshots to a smaller size, frame them, and feather their edges to blend onto a background. Windows and icons can even be shot with a "backdrop" that isolates them from the desktop and captures their transparency and shadow.
Constrictor can also be useful to designers for seeing how a layout will fit on a screen of a given size. Just set Constrictor's frame to be the size of the screen you want to simulate, and then see how your content looks inside it. Since the frame is transparent, you can edit your layout right through the frame.
Constrictor is quite configurable. Being a Stick Software application, Constrictor provides you with a preferences panel with various features you can customize at your own liking.
