I created this design as part of a ‘Call To Artist’ event for the 2004 da Vinci Days poster contest. The design started as an abstract image of a tree (or as others have described it: the Star Trek communicator pin the crew wear). I wanted to repeat that pattern 12 times, putting one behind the other and 30 degrees to the left. Similar to when you take a stack of napkins and twist down on them to fan them around.
