Hi folks,
been messing around with Quartz Composer, and have just completed my first simple FX plugin for VDMX. It's a variation on the newBlur comp. mrRay sent me, but this one does video-feedback-style moving trails too.
If anyone is interested in using or poking around inside this comp, I've stuck it on my website at

I actually realised that it's possible to create a controllable feedback effect without writing any cikernel code, by using an instance of QCs dissolve object, and a blank image as the target image. Don't know if this uses more GPU power than mrRay's cikernel code.
I'm really excited about QC now
