This evening I have been experimenting with generating quick spontaneous patterns using Adobe Illustrator.
The idea was to play with manipulating an image by cropping, reflecting and distorting.
I began with a very crude, mindless doodle (a squiggly line). I then took screenshots and used the image trace function in Illustrator. I began experimenting by removing parts before flipping the image both horizontally and vertically and arranging them in an order I felt looked interesting.
The computer really does do all of the work, but the simple process shows how through continuous exploration (or play!), unexpected results can occur that can become starting points for more developed work.
