Friday fun

Here's somthing that can take hours out of your day, if you get into it: JacksonPollock.org.
It looks like a blank screen, but just move your cursor into the page. Slow makes thicker spots, fast makes thin lines. Click to change colors. I wonder if there's any way to save your creation (it's Flash)?

Or, how about this? Yes.com can show you what's playing on a radio station near you; a U.S. map constantly changes as songs change on the stations. Or search for your favorite station, or stations by ZIP code, to see what's playing.
