The idea came to me a while ago, actually. I was in the train, on my way to the university, and, not surprisingly in the Netherlands, it rained. The drops on the riding train made trails on the window and when the train slowed down and stopped, the trails dropped down, instead of going horizontally as they were doing while going at high speed. It was fascinating to look at and the pattern that occured was awesome. When confronted with the topic 'flawed' I wondered what to do and suddenly I remembered that rainy day in the train and this is the result.
Enjoy!
