Wow, hadn't heard of TkZinc. That looks incredible. Another cloud
for my Pd heaven : ). As I've been writing, I'd really love to create
GUIs entirely with Data Structures - I'm not sure how much of a
performance hit that causes but the opportunities for customization
are much richer when it's turtles all the way down (where turtles =
Pd). Is TkZinc feasible for replacing the whole GUI? It seems to
support all the platforms Pd does.
