Inkpoly is a screensaver for Wii homebrew. It’s kind of like a spirograph but with overlapping regions that fill with the even/odd fill rule. It makes use of the ftgrays anti-aliasing rendering engine from the FreeType library. It is all done in software, no 3D at all, making use of the 4:2:2 YCrCb bitmapped screenbuffer for the display. It’s using cubic bezier curves to define the shape to render.
