me and arlo and lilia made a projector with a glass slide of MICR magnetic
toner particles suspended in veggie oil for a party. (sort of ferrofluid)
here is a video of the result.

at 2:55 you can see us starting to play with the magnet, which causes all
the little filings to change direction to follow the magnetic field.
at 3:55 you can see the whole screen get lighter and darker as the magnet
causes the filings to line up in the path of the light so they have a
smaller profile, and they don't block as much light.
at 4:33 you can see the projector and the magnet being moved around it
near where the slide is.
