I've spent some time over the past few days, and rewrote MandelPod. No longer will it seem to hang your iPod while it draws...
The old module was ported from podzilla0. The new one was rewritten from scratch, to use TTK directly. It also uses TTK's gradient functions to generate the palettes to be used for rendering.
It's also got a switch to see the associated Julia set as well.
