This is what I was showing at SIGGRAPH, intended for a bit of instant gratification. It contains three image-generation components from Jarrett Smith, a radial blur component from Ben Voigt, an image switcher, a combiner, plus miscellaneous other parts from me. It is a complete .toe file, so you will have to save it to your Desktop and start it separately.
You can play with the gadgets as-is, or delete it all and rebuild it from scratch using the gadget palette on the left.
