I'm always on the look-out for cool websites. This one was brought to my attention a little while ago. Anyone can create art with just a few swipes of your mouse. It's free so try it out for yourself.
There is something very 'Rorschach' about this site. No matter what you create, they'll all look like flowers, for the most part. It's still fun and calming. Perfect if you're at your desk during a work break and need something to unwind for a moment.
