Wow! That's pretty cool! I have always been fascinated with crop circles, although I think they are just creative pranks as opposed to UFO's. Now they actually have computer programs where you can design crop circles or corn mazes and the system works with the laser-guidance system on modern tractors.

The tile on my porch has seen many an epoxy spill, yellow glue, paint, etc., etc., and always comes sparkly clean. I just wish the guys that built the porch had angled it a few degrees away from the house. It kind of slopes the wrong way and pools water really bad during storms.
