Can anyone recommend tools for getting into generative art?

I have tried using a gamedev engine. It worked OK, but there have got to be better suited tools out there.

OpenFrameworks and Cinder are probably a bit more powerful, but more difficult to use (built around c++).

I also like PaperJS, which is built around JavaScript, but doesn't have the performance of Processing and OpenFrameworks.

Finally, you can just use raw drawing APIs (such as Canvas in the browser).
