Cinder – a C++ library for programming with aesthetic intent
Cinder is fantastic. I spent the start of last year fixing an old iPad app that was built with it called Planetary. It’s free on the App Store if anyone is interested.By pure chance I ended up getting in touch with the original developers and a couple of museum curators from Cooper Hewitt who helped acquire the original code as digital art work.
