re:how to get data from a webcam to see how feasible that is OpenCV (computer-vision) has a package to access a webcam with python, it also has video loading capabilities, which I think is what we're analysing. I've not used OpenCV, but should be able to learn it.

Ideally the data-stream would just be a large 3D array of intensity at each point on the screen, over time.

package that can load mp4 (likely saved from webcam) as a "mosaic of images" in python http://zulko.github.io/moviepy/

this sounds like the above goal, if it is true

issue #10 appears to have superseded this issue we have also successfully achieved initial data capture, with this issue having correctly guessed the viability of webcam capture
