Subblue (Tom Beddard), released a mandelbulb fractal raytracer as a pixelbender plugin as well as a quartz composer patch, both for download. I was playing around with this in AE the other day, it makes fantastical looking fractals with high antialiasing its slow but super sweet, and there are also lots and lots of attributes that can be keyed over time in AE… yes, it is nerdy fun.
