First animated fractal on CPC (only static ATM)... Congrats!
So Osmium is Optimus+Ham?

Looked very nice on the bigscreen! I remember saying to someone that for me there is a kind of obscure and mysterious aura around CPC scene, which isn't a bad thing, rather the opposite actually.

This worked well on the bigscreen. I cannot estimate the technical feat here, but my guess is it's significant.

Damn fast. Some technical info would have been nice (didn't read any on the scroll).

I might post some explanation soon in my youtube channel. But in a nutshell, it started as a C experiment to minimize number as much as possible to fit in 8bit range and try to create precalc LUTs for all the muls, trying to fit that all in small CPC memory, covers at least two separate 16k areas but in weird configuration, then several z80 tricks, among with storing the LUTs in such way that minimize reading, even with passing -32 to 32 X and Y values to the LUTs, and few more smaller z80 tricks, finally after that I did 2x2 subdivision, calculate every 2 pixels, if the same fill the block, else go pixel precision.
