My ideas for London Pleasure Gardens is an army of flying pigs. Based around the rave egg/pig concept that I've been rocking in Haha-fresh workshops, but solar powered, and autonomous. Kinda also like my Insect in a jar. And definately inspired by Ralf Schreibers Solarsoundmodul, and kulturgueter-schuppen sonnensanger seen below. + Thanks to kulturgueter-schuppen for the donated components.
*EDIT*
Same idea submitted to Brighton digital festival
