I love computer graphics , i like a lot all the aesthetics of the things people do with VVVV , processign and that kind of software , is not animation and characters , its more like living patches , patches that do things over time , generative art, music reactable , interactive art.
Can blender do this kind of thing ?
what limitations do i have comparing with vvvv or processing ?
One limitation compared with processing etc ( or a major advantage, if your project suits 3D ) is that everything you do will be displayed with real-time 3D graphics, rather than being processed within a 2D image.
As Blender can use external python libraries, you can do some pretty cool stuff with Blender.
