As part of a gig this weekend, all eight participants had digital cell phones. (These were kindly provided by the local Cellular One office.) I'd never played around with so many cell phones before and I discovered a property that other loopers might be interested in. When I phoned other participants in the same room, I quickly noticed a significant delay when speaking on the phone. I didn't measure it but it was probably 1/2 to 1 second in length. So I took two phones and held them in a "69" position :). This created a feedback loop of about 1 to 2 seconds. I amplified the set-up with a tiny "tie-clip" style mic and sent it to the PA. You could whistle, speak, etc into the phones and generate a decaying or sustaining signal, depending on how close together you held the phones. Quite awkward, but fun!
