[hackerspaces] "Inductance" - real or fake?

[dosman]

Saw this amazing video on a blog and am as intrigued by this as  
annoyed by the lack of details I've been able to find so far. I'm  
posting this here because it looks like a hackerspace built this  
project.

Inductance:

Physalia claims to do 3D animation but also appears to do physical  
hacks too, so I'm 50/50 as to whether this is a real device. It looks  
like they are varying the (weak) field of the electromagnet in the  
ball along with the the field in the ceiling coil. I'm not yet  
convinced this is possible.

Thoughts?
