great Julia optimus!
it was so good not to be lonely :)
Ossom :)
First animated fractal on CPC (only static ATM)... Congrats!
So Osmium is Optimus+Ham?

Yeaaaahhhh ! Well done Optimus. You did it.
Animated Julia -> Optimus Prime!
Nice 6k demo! Congrats!
Good framerate!
Good Demo !
It was cool to see at Decrunch2022.
Nice one!
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.
Great work with only 6kb!
cool stuff - good animation - i like the sound
nice one,
music sounds cool, AY/YM rox!
music sounds cool, AY/YM rox!
More 8 bit stuff please.
nice demo! Congrats!
Stunning!
Rulez!
Yes!
cool
cool stuff, and cool platform!
This worked well on the bigscreen. I cannot estimate the technical feat here, but my guess is it's significant.
Nice!
8 bit fractals!!
Great prod!!!
Great !
Nice!
Nice prod, CPC still excedeed
Very enjoyable for the size and well suited music
What everyone else said, basically. Plus: A new group on the CPC, yay!
6 kilobits of wise coding ! Nice music and logo too !
Great! Nice to see Optimus back on CPC :) Looking for more from you two guys!
OK.
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.
Long expanation video showing various improvements of the effect from the very slow C early prototype to the last assembly version.

Yeah! Optimus, we miss your bigger CPC productions, but this is sweet and inspiring. I think I have an answer.
I don't see the pixel precision, though. My guess is 48 x 48 x 8 iterations.
Very nice music too, congrats Ham!

bravo !
Just discovered it. I'm looking for the next one
Impressive fractal routine for a 8 bit machine. Good one!
Thanks Optimus for proposing original mathematics-based effects on CPC once again!

Enjoy!
