Visualizing TV Dialog Using Closed Caption Data

I used Arduino + Video Experimenter shield + Processing sketch to dynamically construct a "word cloud" from the closed caption stream embedded in a TV broadcast (NTSC). The Arduino decodes the closed captions and writes the words over a serial link to the Processing sketch running on a computer. Project details :

Ooh, I like that. Very neat.

Was the text from an episode of M.A.S.H? (Hawkeye)

Yes, it was! Nicely done.
