This is a Mandelbrot set generator, you could have seen them on other platforms as well e.g. FractInt for PC.
I wrote it some time ago for PC but never released it. Then I accidentaly downloaded devkitPro and here you have it :)
Thanks to Daniel Egnar, Tom Schumm and Jussi Kantola for their palettes.
You can load it with Front SD ELF Loader, I haven't tried the other possibilities but they should work.
