Just want to thank all the people from Garagecube for their great software!
Definitely my most well spent money in a long time.
It's extremly powerful, easy to learn, a pleasure to work with and.. it gives you a lot of artistic freedom.
Used it with this setup:
G5 Quad, 4.5 GB RAM, 3x GeForce 6600 videocard
OS 10.4.10, Quicktime 7.1.3
