Ferrofluid is a venom-like liquid that was invented in 1963 by Steve Papell, a NASA engineer. Nowadays, it is used to make a bunch of fun desk toys. The SPIROK ROBO is a LEGO compatible ferrofluid music visualizer that doesn’t require a Bluetooth connection to work. It has a handcrafted dome glass bottle and an ABS body.
This ferrofluid speaker can be used for up to 8 hours. You can use this to display your favorite LEGO minifigures. This project is getting funding on Kickstarter.
