Hi Mr G,  I've used Isadora to make several videos as well as for an interactive space for an art-science lab in the city in Auckland back in 2009. Recently I wanted to use it for a stage installation but found my equipment ( night vision cam and Canopus) weren't compatible any longer with computer etc and so I've upgraded to Isadora 3 with web cam and kinect. I've also been wondering if there are other Isadora users in NZ --so would welcome chatting with you. I'm in Auckland.
