"Hi, Damn Glad To Meetcha!"

This art display is in front of the SF Main Library. Actually, it's only HALF the display. There is another outstretched bronze hand about 15-feet across from it. The idea is you, and a partner, face the library and clasp hands. Then with your outside hands you each grab one of the outstretched bronze hands -- completing an electrical circuit at which point music comes blaring to life. Motown was playing while I was there.
