Cinder is a peer-reviewed, free, open source C++ library for creative coding.

Cinder provides a powerful, intuitive toolbox for programming graphics, audio, video, networking, image processing and computational geometry. Cinder is cross-platform, and in general the exact same code works under Mac OS X, Windows and a growing list of other platforms — most recently the iPhone and iPad.

Cinder is designed to take advantage of platforms’ native capabilities whenever it’s possible, and relies on a minimum of 3rd party libraries. This makes for much lighter, faster applications, and means Cinder apps get free performance, security and capability upgrades whenever the operating system does.
