Morpho Towers

I have just come across this video showing something called a Morpho Tower, this device, created by Sachiko Kodama, is essentially a computer controlled electromagnet with a liquid ferromagnetic material surrounding it in a bowl. When it's turned on the liquid climbs up the spiral cone to produce some very beautiful patterns. I don't know if this will ever be sold to the general public but I would buy it over the lava lamp any day. Check out the video.
