While poking around Craig's List the other day, I stumbled on an 
Items Wanted post from an artist in SW Minneapolis.  He's doing 
an art project -- a sculpture, I think -- that requires a 
bazillion keyboards.  I took the opportunity to offload a pile 
of dusty keyboards from my basement hoard.  He's coming by next 
week to collect them from my doorstep.

If you have excess keyboards, he wants them bad enough to come 
to your house to get them.

Here's his post on Craig's List, dated July 3:
