I came across Danielle Navarro's beautiful R/C++ implementation of IFS fractals and wanted to understand how they work by porting it to C. After that, I made modifications to compile to WebAssembly so you can try it directly in the browser without installing anything. You can generate static PNGs with the C version or interact with it live via the WASM demo. The math behind IFS is fascinating: simple geometric transformations create incredibly complex patterns. I hope you like it.
