Randomizing patterns

Irritated by the many pseudo-random patterns that I encounter on a daily basis, and intrigued by the possible surprises that might appear, I started creating 'real random' patterns. No more random-looking patterns that are repeating after all when you look closer, but patterns where all parts are really different! Also, every pattern is truly unique. Because of all the random effects, it is practically impossible to make exactly the same pattern again. At first I started randomizing the locations of the shape corners, but random changes in the (shade of) the colors followed soon!

Purple pattern cupboard doors

My very first steps into pattern design. My girlfriend and me were looking for a nice design to use as decoration for the doors of a cupboard in our living room. We could not find a design with a pattern and color that we liked, so I decided to make one myself: a basic pattern in purple, build up from diamond (or rhombic) shapes.
