object reference graph visualization

Hi--
I've written an interface between Squeak's interpreter simulator
and the Walrus 3D graph visualizer. It's turning out to be very useful
for exploring the relationships between objects. I made a fun little
demo movie; check it out at http://netjam.org/spoon/viz/.

that's lovely. Could you define the other hydra in the graph? The one
beautifully rendered hemisphere is the Symbol table but what of the
other two or three double-headed hyrda visible at the end of the movie?
TIA

Those are method dictionaries. And there are several more, off in
the distance to the left and right. Note that this is "hyperbolic 3D
space", in which the minimization of distant objects is exaggerated
(so that it's easier to focus on nearby things).
Since making that movie I've come up with a much more meaningful
spanning tree (the blue lines) for the graph, one which is biased
toward subclass and instantiation relationships. I encourage people to
explore around in it with Walrus... it's fun to get a more visceral
sense of a place with which we're all familiar but has never been this
visible before. :) See http://netjam.org/spoon/viz for links to the
new graph data and the Walrus graph visualizer.
thanks,
