Very cool project. There is a video of it in action[0] at the bottom. This is something that screams Kickstarter to me.

Ferrofluid is unstable iirc. I wonder how long this fluid lasts.

This is really cool. I hope someone makes a commercial version of it.

I experimented with making a clock using ferrofluid previously. I was inspired by this clock [0] but put off by the price tag.

Generally the main issues I found were that it degraded over time and I had real trouble with ferrofluid smearing on the container.

Will have to try again now!
