New effects for Photobooth and iChat!
This tip requires Mac OS X Leopard. Apple released many new iChat and Photobooth effects in Mac OS X Leopard, but it would be cool to have even more. There is a great third-party application that adds 48 new effects. According to the developer, it works for G5 and Intel powered Macs (some G4 might be supported). The integration is great. Once installed, it works and looks just like effects from Apple. The collection of effects is called "More iChat Effects 1.2" and can be downloaded here from the Apple site.
