When I see this great piece of work, I remember that:
I tried some circle stuff:
Using polar coordinates, directly mapped (without backconverting to the form a+bi) to the x y and z coordinates
the imaginary part goes to infinity rather often, but the real part is nice
sqrt(1-(x*(-1)^y)²
an other formula, resulting in more complex shapes:
(1-x*(-1)^y)^(((-1)^x)/2)
try them out They're nice.
I'm not yet sure how they look, if you map them back to the rectangular form... (r*e^(phi*i)->(a+bi))

btw, if you want to tryout picogen (if only mkheightmap), if given a super short howto to Sha-X-doW at [link]
I'm trying out linux right now...
Dled Pictogen...
How can I open the binary? Doesn't want to neither work via single nor double click...

Cool!
Hm, no clicky at the moment, you have to work on the cmd-box/shell.
I have uploaded an Windows-Installer at [link] , which takes care of enabling you to type "picogen" in whichever directory you are.
Under Linux, open a terminal, and type
# cd <directory-of-picogen>
or create a symbolic link to picogen into /usr/bin (see above link).
On which GNU/Linux-Distro are you?

Linux Mint
Do you know it?
Something like an Ubuntu edit.

Ah yes. Haven't tried it, but Ubuntu-based is Debian-based, and Debian is what I run on my box
Mint looks nice, probably due to the green colors
I am preparing a minimal GUI for picogen, with just some text-editing and a preview function, and maybe with a predefined-text-blocks-functionality. Not Teh Gui To Bind Them All, but it makes life easier than shell-hacking (especially because you can put the function-code onto muliple lines). (I plan to use a stylish, open-gl based custom GUI-framework for the 'real' gui)

sounds cool

hmm, i tried out with "picogen mkheightmap -p -Lhs "(sqrt (- 1 (^ (* x (^ -1 y)) 2)))" -n -i", and the -i says the min-value is 0, the max-value is one, but the result is all black.
for which value of x, y does it look good?

It seems that I have lost the actual formulas :S
Those I wrote here seemed to be wrong...
I have to find them again - especially the second one.
(The first one was like half-sphere-bumps...)

ah, okay, problem was the term -1^y, i guess ...
i'll try with mkheightmap right nooow
