I have been hear­ing more and more about VVVV. If you are a fan of Pro­cess­ing, then you’ll surely be a fan of VVVV. The results are amaz­ing, both the screen­shots and videos, it is worth a look for its inspi­ra­tion alone. And if you’re inter­ested in a visual pro­gram­ming inter­face for real-​time video cre­ation, this is a fas­ci­nat­ing soft­ware:

vvvv is a toolkit for real time video syn­the­sis. It is designed to facil­i­tate the han­dling of large media envi­ron­ments with phys­i­cal inter­faces, real-​time motion graph­ics, audio and video that can inter­act with many users simul­ta­ne­ously. vvvv uses a visual pro­gram­ming inter­face. There­fore it pro­vides a graph­i­cal pro­gram­ming lan­guage for easy pro­to­typ­ing and devel­op­ment. vvvv is real time. where many other lan­guages have dis­tinct modes for build­ing and run­ning pro­grams, vvvv only has one mode - run­time. vvvv is free for non-​commercial use. Com­mer­cial use requires a license. Get the latest ver­sion from the Down­load section.
