I keep a folder of random images I like form all over the internet. Every few minutes the background on my machine switches to one of them at random. I've kept this folder since 2008 and, as you can probably imagine, it's full of literally thousands of images.
Today I saw a random piece of art full of neon-colored, cocentric circles overlapping one another. It wasn't exactly what I've recreated here, and there was definitely more to the scene, but that was the impetus.
