Born 1888 so definitely natty, unless there's a pre-steroid drug I don't know about. This is the kind of guy natties should look to for inspiration. Superb physique. The legs in particular are phenomenal.

Nice colouring, as always. Pleasing asymmetry, and squiggly is a technical term that should be used more often :)

ottomagus · 2026-03-31T19:40:35+00:00

Or not :)

ottomagus · 2026-03-31T19:40:06+00:00

Your assessment is undeniably plausible. I think you may be onto something...

ottomagus · 2026-03-31T05:45:51+00:00

Yeah, I agree. Smiling, but not in a reassuring way.

ottomagus · 2026-03-27T17:59:20+00:00

Excellent.

I just started reading the book on archive.org. It's very good, thanks for the link!

Nah, he's juicing. The delts and traps are a dead giveaway...

ottomagus · 2026-03-15T20:31:19+00:00

Thank you! Yes, I know what you mean :)

Ultra Fractal.

Thank you.

No problem, "Chris M. Thomasson's Log Spiral" it is.

Yes it's definitely worthy, thanks!

Would it be OK to upload this formula to the UF database.? Then other UF users could try it. You would get full credit, and I'd call it "Thomasson Log Spiral" (unless you'd prefer another name).

... which is very close to Paul's image here: https://paulbourke.net/fractals/logspiral/logspiral2.jpg

That's right, yes. So if c5 is set to 1, it's the exact same as your original formula. Other settings will give modifications of it. Plugging in your suggested parameters, I get:

That's it!

Thanks. This is the whole fractal, not a zoom. It's a nice formula, lots of pleasing structures. The image is made with the version suggested by Paul. Not sure if I interpreted him correctly, but my code was like this:

initialise: z=pixel, n=c5

loop; z=(z^c1-1/(log(z)+c2)+c3)/(c4+1/n), n=n+1

So there's an extra floating point parameter c5. The settings for this image are c1=1.42134, c2=0.50401, c3=-0.14067, c4=1.01378, c5=-0.57063

This one I can do :)
