Paint like the master. Give it a shot. Alas, I haven't found a way to drop cigarette butts and other stuff onto the canvas. Other than that, it works fine. This link was lifted from the ninjas' hangout (www.bookninja.com) while they were out doing what ninjas do.
While I'm at it, I might as well offer up a few more cool links:
http://www.rheostaticslive.com/ - an amazing collection of Rheos concerts to download. They always were a great live band.
http://www.sunspace.org/radiolist_en.html - a list of all the radio stations in the Toronto area with frequencies. Handy for someone like me who can never remember the university stations' frequencies when I go looking for something different. The site can be toggled back and forth between english and esperanto which is about as random as it gets, I guess.
http://www.mapmywalk.com/ - if you want to know how long your long walk was, try this.
http://www.hermitary.com/ - where hermits hang out. Just don't tell anyone. They don't want to lose their hermit cred.
