As you may see from this site, i am NOT a programmer (nor a cartographer), the best thing i did was a map projection visualizer in scratch (or a scratch mod, whatever). (There are tooltips, hover over the screenshots!)
NOTE: I've also stumbled upon some map projections using my thingamajig: (sorry for the watermarks, just felt i had to add them :P)
I've made a Mandelbrot Renderer using the same rendering technique, it's based off Wikipedia's pseudocode. (Trust me bro B))
I've also found this weird Burning Ship looking ass wannabe fractal
I have no idea how to make a shader so probably this is the max i can get with programs like this
I have no idea how to fucking rotate a equiretangular map wdym i have to convert it to spherical coordinates
