Well there's the important stuff:

And then the less important stuff, like being able to patch 15 out of 
the 28 demos shown here:

Essentially everything except the ones with gradients and text, but 
those features can be added later.

It's generally not as high level as Raphael-- for example I ported the 
Raphael code to subpatches for the easing demo, and I'm just using 
[line] to do the animation.  However, it would not be too hard on the Pd 
side to add an "animate" method.  In fact that'd be quite efficient as 
you'd only be sending a single message over the socket and letting the 
GUI take care of the details.

Also, I'm instantiating scalars inside object boxes.  Since the user can 
send messages to update shape attributes straight to the parent draw 
command, this means he/she can do an end-run around pointers for 
prototyping.  So essentially you have the ability to dynamically change 
visual attributes on the class level (i.e., the parentwidgetbehavior) 
and on the object level (for the specific scalar, as you can currently).

There are still lots of details to get right, like handling groups 
properly, but the basic stuff is there.
