MulleSight is a tiny application for capturing pictures taken with your iSight camera (others may work as well). It features a complete AppleScript interface, so you can do all sort of stuff with it.
What's new in this version:
New in this version is the ability to select an arbitrary (or the last captured) image as video input source. This allows you to apply all the effects afterwards, which is quite nifty if you want to give your photos some finishing touches. A bit of the user interface has been improved, also the localizations have been improved dramatically. Last but not least, there's a new About panel which totally kicks ass! ;-)
