i have an alter/copy/pass photocopy art project going around. i made a photocopy collage and sent out a whole bunch of copies for people to alter, copy, send back to me, and pass on. i have a bunch scanned on my web site, and about 3 times as many waiting to be scanned one of these day. if you're interested, let me know and i'll send one to you. it's really fun to see them come back in different forms.
