Sculpting with Fluid

Ferrofluid, that is. Here’s Sachiko Kodama & Yasushi Miyajima having fun with helical iron shapes, an electromagnet and a pool of ferrofluid. 

More here. And some military applications.

I saw one of these at SIGGRAPH. It's rather amazing, and the video doesn't even do the coolness justice.

Nice. I might make ferrofluids the subject of my next 'feature article' (only 650 words!) for Nanomaterials News. It's an interesting subject, with many practical applications.

I might make ferrofluids the subject of my next attempt to take over the world. That is, I hope, a practical application.

[Francis Sedgemore]

I always had my doubts about you, David.

[David]

There’s nothing to worry about. No, really. Mine will be a benign rule. Firm, but benign. I shall smile upon my people from a throne made of my enemies’ bones.

[Francis Sedgemore]

How many failed attempts so far?

[David]

There’ll be none of that kind of talk under my firm but benign rule.

I suggest a decade as Chancellor of the Exchequer before going for the big one. Your current impetuousness could easily get the better of you.

[David]

I can see my first official duty will be to smite the unbelievers.

It reminds me vaguely of the semi-sentient planet in Solaris. The novel, not the movie.

[Francis Sedgemore]

Semi-sentient? Sounds like Earth.
