While I find that I like my ferrite-based Kickstarter art projects to be a bit more automatic, the Ferrite Interactive Liquid Sculpture is still pretty cool. It’s a tube containing a Ferrofluid - a suspension of ferrite particles - that is shock-resistant enough to survive a few tumbles. You can use a magnet to create odd shapes, experience the magic fo magnetics, and you can put it on your desk and toy with it as you wait for 5 o’clock to roll around.
