CatEye is a free collection of video effects for Leopard. Working equally well with iChat and Photo Booth, contains the three sets of eight video effects (shown below): RetroPixels, Love For 80s and Bent Pels. Version 1.001 added two more sets, BoobToob and FewTile, for a total of 40 effects. BTW and FYI, OMG! If you like these effects try DotMatrix (400+ photo effects) and Q@mera (200 photo effects).
CatEye is very easy to use. 1. Quit PhotoBooth and/or iChat. 2. Install CatEye .QTZ files into /Library/Compositions. 3. Reopen Photo Booth to find the new effects available.
1. Use Finder to open the /Library/Compositions folder. 2. Identify any/all CatEye effects (they have .qtz file extension). 3. Throw the effects into the Trash and empty it.
