> a) change color
I would rather stick with black. If you change color now, systems will start
to look like patchwork quilts, and not in a good way.
> b) add graphics
That's fine with me. Bonus points if the graphics have some meaning. :-)
> c) change knobs/add colored knobs
> d) not be "on grid"
Those are both fine with me, too, although I didn't much like the baby-blue
Buchla knobs.
> e) place jacks somewhere except across the bottom
Hmm, well, if there was some compelling reason to do so. I suppose this
could tie in with the graphics somehow. The graphics could tell you
something about the signal flow through the module, and the jacks could be
placed appropriately.
