My daughter (college age) just went to a Warp Tour concert. One of the
highlights was a graffiti wall. People could give the assistant an ID,
and they would receive either spray paint or permanent markers to add
to the big L shaped wall. They got their ID back when they returned the
art materials.
Might be fun for an open house project....i wonder if it would work for
a parents "back to school night" as well.
