i drank the kool-aid has posted a little guide which linked to Momo’s last QC tutorial, “Lighting 3D Cubes and Moving them with Audio Input“. Unleash Your Inner Creativity (and Programmer) with Quartz Composer is a very quick and simple overview which covers loading an image, scaling it and moving it around, but this is definitely enough to get you started and get the juices flowing with some more experimentation, so if you haven’t opened QC before because it looked too complex, now’s the time.
