Thumbscrew

Here's a really cool new piece of freeware. Thumbscrew "allows you to drag and drop images to create rotated thumbnails with borders and drop shadows. Maximum angle of rotation, maximum thumbnail bounding box, and border size can all be set before creating thumbnails."

It works on Mac OS 10.3 or later.
