the common parlance is wrong and creates confusion! Chemists give you shit if you talk about nanomachines because they'll say that brownian motion will blow your nanometer sized machines around like a hurricane. But since many so called 'nanomachines' are actually bigger than just nanometers this is a nonissue.

And what the fuck does in 3d mean? You make a cube with solenoids on all faces? Great you now have a cube that makes light bumps of ferrofluid move across it. It's going to be extremely difficult to many anything other than a small bump of ferrofluid because magnetic forces still decay at something close to the inverse square law.
