Things I might do on Scratch will be put here, updated when necessary . Sierpinski Pentachoron [5-cell] . Tri-subdividing BSP . [long term] Z80 CPU + Assembly Emulator [1 project], with TI Basic interpretation and UX [Remix] with potential 8xp URI generation ( The file format / charset encoding is not publicly available by my knowledge, so this is a big maybe ) . Fourier Transform (Discrete / Fast) Demonstration For Sound Emulation . a remix of the old "ROPE FISH" project with added progressive gameplay similar to Spore's cell stage / hungry fish . Voroni / Delaunay triangulation / worley noise [ I haven't looked much into this but it looks interesting ] . Data encoding for certain file formats [ Huffman, Discrete Cosine, etc ] *(A PNG decoder is in progress) . Guide project - comparing PRNG methods . 3D Rasterized (BSP) Engine, with file opening (images models, [animations?], etc) . 3D Raytraced (BVH) Engine. This has a better time complexity with respect to tris than BSP, making it likely faster for very large scenes. . 3D STTF (BSP) Engine builder, that creates a data uri .sb3 project with built-in STTF images from a 3D file's tri UVs and source images. This one would be especially complicated to make, but would be very fast, even without Turbowarp. . a CAD software based on the above 3D engine. Something as simplistic as picoCAD might be able to run without Turbowarp
