I've been fooling around with rubber bands since Elastrix 2 and Dan Harlan's VHS videos appeared.
Not to take anything away from Dan's videos, but this lecture by Joe is a definite tour-de-force on
rubberbands!
Joe starts from the very beginning and goes through effects in great detail,
laying out an entire theory and plan for not only learning but performing and remembering
everything.
If you've never worked with rubberbands, this is the place to start. If you
already do, you'll want to get this to stay on top of it.
