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.
