Dynamic Generation of Images and Video with Ruby-Processing
summary
Prototype builds that actually output files not promises it uses Ruby-Processing wrapped as an 18MB JRuby gem, runs with rp5 watch to iterate sketches, and consumes simple jobs from beanstalkd serialized as YAML so Rails can push text and filenames. The worker measures text, uses the silk screen font, rotates and saves PNGs, and can capture webcam frames for watermarking video. Deploy notes include headless rendering with xvfb and process monitoring with god; the demos work.
