Graphics and fractal programmer here

Cool, have you tried to keep also track of colors of each shape, also relating it to the iteration count?

Lovely stuff!   It's very addictive isn't it, developing one's own fractal program!?   Potential new features flood into one's mind and demand to be implemented!  But the joy when, after messing with a couple of lines of code,  a new and beautiful image appears on the screen, is hard to beat!

If you're not planning to sell it perhaps you'd think about open-sourcing it and putting it on Github?   That way others could learn from your code and develop it in different directions...
