vvvv is a hybrid graphical/textual programming environment for development and easy prototyping. It is designed to facilitate the handling of large media environments with real-time motion graphics and physical interfaces, video and audio that can interact with many users simultaneously. The language used vvvv knows only one mode: runtime. Turning the notion of stopping a program to recompile it into a footnote of the early days of programming. Compilation happens behind the scenes doesn't interrupt your flow of work. Responsible for its development is the vvvv group.
