Using the camera as a scanner has a long history in satellite cameras and other aerial photography

It would have been pretty easy to use a horizontal line scanner to get image speed.

In any case, it seems that using a full frame video would be much easier to post process since frame to frame correlation tells you everything you need to know about motion.

I love this so much! This is such a cool hack, just for the sake of it. Amazing hacking and amazing art!

In the preso, she has said the full size output is on the website-

can anyone see what that link is? I didn't find it on the video page, but I might've just missed it.
