There's lots of cool two color designs that would make dramatic quilts. I was looking for a maze generator to make printouts with to amuse my young son, and when I found Unikatissima's Maze Generator applet
, I was inspired to make a maze quilt.
Unikatissma has a Random Squares Pattern Generator
that looks fun. I also find Cellular Automata patterns a good source of inspiration for two color designs, and my favorite tool for exploring them is Mirek's Java Cellebration
. My next quilt is planned based on a "Life 012345678/1" rule automata.
