This is a toy that took me a weekend and a bit to get going. I’m using the Cinder library, which for the most part keeps itself to itself, and C++, very badly abused C++ at that.
It’s only on the Mac at the moment. I’ll see if I can get it going on the PC and upload a build here if I can.
Grab the Mac build here.
Unzip it, stick it in Applications or something and remember to sort out your security settings to allow running something by a nobody. (After you’ve run it, do remember to restore your security settings, OK?)
