Check out this crazy brush!

I love weird, esoteric tools, and this is one of the weirdest I've ever seen! I saw it at my local art store, Blue Rooster. I get dizzy just looking at it. Apparently an artist has them custom made to paint special swirly designs. I was trying to think of other fun crafts or projects you could make with a brush like this, but I can't seem to come up with anything. It's like a physical manifestation of an art oxymoron.
