Thank you for doing this.  I've been wondering why there was so little discussion of the canvas tag on this list.  Perhaps we were all waiting for David Hyatt to come back with the proposal he promised.  I have tried building the WWDC version of WebCore just to begin trying out the canvas tag, without success, but now it looks like Mozilla will be offering a usable canvas tag, so I'll try there.

[...]you can think of <canvas> as a programmable image tag. In that light, it's reminiscent of the XBM images generated using <img src="javascript:genxbm()"> tricks developed by Bill Dortch back in the Netscape 2 era. All of which is to say, we really should have implemented this kind of tag in 1995[...]

Amen.  It's about time, and I'm glad to see this as part of the much-needed WHAT activity.

More when I have something substantive to say.  I wanted to get the kudos in first.
