This example from the nodebox site worked in shoebot first time (always nice).

http://nodebox.net/code/index.php/Fireworks

So might be worth including .. as always I'd like it to have better performance (or at least progressive rendering), but c'est la vie..

Nevermind, changing n = 80 to n = 50 made it work for me.

Interesting result, it's possible that something pathological could be happening with memory, might be worth seeing how much memory uses when running different bots.

I tested this on the weekend using svg output and got an 11mb svg !

When I tried to open this in inkscape, it used all the memory before crashing.

PDF output was fine, + running in window mode.

There's probably something suboptimal in the cairo use SVG.
