Jonty, I'm mixing hacking and art and becoming increasingly aware of the self-segragation of creative work into either "art" or "hacking". Here in Vancouver, for example, we have "art" events (art crawls, galleries, etc.) and "maker" culture (maker faires, hackspaces, etc.) with almost zero crossover. The presumption is that art will be expressive, shown in public, and saleable, and hacking will be insular, self-funded, and have limited appeal outside other hackers.
I've exhibited technological work on a small scale to an art crowd and gotten a positive response, but I worry that going further on that side of things will be an uphill battle. The knee-jerk response may be "that doesn't belong here".
Have you encountered this kind of pigeonholing? If so, how have you approached it?
