Free paint replacement on OS X again

OK, here we goes the free MS Paint replacement on OS X again. There are Tux Paint, Pixen, Seashore, InkScape and Expression.

IMHO, Expression is the best, and it is from Microsoft. My only problem with Inkscape is X11. I don't like X11 programs.

There are two painting programs came with the OS X 10.4 install CD, but you can only get them if you install the developer kit. One is at /Developer/Examples/AppKit/Sketch and the other one is at /Developer/Examples/Quartz/CarbonSketch. Enjoy your compiling.

SVG ability in Safari 3beta and Firefox 3 Alpha

I tried to run both through the W3 SVG test suite. Of course both of them can't render all of the tests, their ability is IMHO on par. But I can't get focus on the URL bar after I run some tests in Firefox.
