Re: Using Breve, Digital Space, Framsticks et al

Tom,

good that you mention this right now.  i was just thinking about what
step to take next and i had decided on getting something graphical to
appear.

on the one hand, D@H is more non-visual than visual, because all of
the evolution happens in the storm of numbers inside the chips while
nobody's watching, so any way to make visualization of the results
easier or snazzier would be good.

i could start sniffing around to see how these things might be done
with the different frameworks you mention, but if any of you have some
helpful hints, inside info, particularly good URLs, motivational
arguments, i'm all ears.  if none of them make enough sense i can
easily fall back on my trusty JOGL interfacing.
