"Pd (aka Pure Data) is a real-time graphical programming environment for audio, video, and graphical processing... Pd was created to explore ideas of how to further refine the Max paradigm with the core ideas of allowing data to be treated in a more open-ended way and opening it up to applications outside of audio and MIDI, such as graphics and video." (Zmoelnig, 2009)
This could possibly be a tool to control the images which is collected from the internet. Looks very complicated.
