Just been at Muscycle Pedal powered concert in Carlton Victoria with colleague Phil Gerner, where we took the still-being-developed bicycle powered twittering machine for an outing. It’s …almost there. Needs more work. We also took over another smaller smoke ring generator, this time based on a kick drum I found in the hard rubbish years ago. Liam Gerner’s band The Allan Ladds incorporated it into their show. Cheesy organ maestro Barry Morgan also got into the spirit. The smoke ring device seemed to produce a kind of religious rapture in small children.
