Coolest thing I've seen in a while.
I'll have a go at this next time I have a couple of millenia to spare:
"1. record a video of your action
2. extract each frame as an individual image (the opposite to what you would do for a time lapse)
3. extract a vertical single pixel wide line from each image (for example a line from the center)
4. stack those lines horizontally from left to right to form an actual "slit scan" image"
I've been there but it seems like a long, long time ago. It's nice to know somebody caught it on tape.
Bill, you forgot "Add eerie music sound track."
The music sounded like a choir of Eloi.
You, always interesting and sometimes it's painful.
Well, you can do it with a camera and a computer, or you can do it with a handful of mushrooms.
Computer is easier on the brain cells, though.
