IFS - Fractal Image Compression
We use insanely complicated mathematics to achieve big compression ratios
Download IFS Application Framework, a freeware educational program
for fractal image coding by Giovambattista Pulcini
(portions by Valerio Verrando,
Carlo Meloni and Riccardo Rossi).
Note: It needs 486DX2/66, 8MB RAM, Windows 3.1 with a 11MB swapfile and a 32000 SVGA driver (at least).
