Thanks - it's a 3D view of a 4D Julibrot which is a complex maths fractal where the 2D Julia and 2D Mandelbrot forms are mixed to give 4 dimensions. It's for the standard fractal formula z^2+c where "solid" is based on orbit trapping, the animation was produced by modifying some of the orbit trap parameters. All done in Ultrafractal.

Oops meant that as a reply:

Hi Rykk, thanks for commenting a second time !!

It's 100 frames, but I went a bit overboard and rendered at 3072*2304 (without AA) and it took around 107 hours I'm going to do another version this time both morphing and rotating using more frames to get a full-view but I'll stick to 1024*768 and increase the detail level (there is some "missed solid" on some of the thin strands that I want to fix).
Thanks for taking time to comment, I'm enjoying playing with the 3D stuff

Thanks Panny - I'm considering doing an extended version, rotating the view as the object animates - it'll take quite a lot of rendering to get a good quality result

Thanks again ! I'm just contemplating spending my spare time over the next couple of weeks on writing a vastly optimised and extended version of the formulas - mainly to get the rendering time down (I'm aiming for a 10 fold improvement).

I envisaged it as some sort of small implant Thanks for commenting.

Thanks - it took quite a while as the full size version is rather large.

Thanks Dave
