US Patent 8228575 - Holographic display using "nanomachines"

http://www.freepatentsonline.com/8228575.html

This patent from Verizon Patent and Licensing appears to me a little bit dubious in terms of enablement but suggests that it is possible to create 3D holographic images using iron-doped nanotubes (referred to as "nanomachines" in the claims) controlled by an electromagnetic field. Claim 1 reads:

1. A method, comprising:

receiving information representative of an image;

calculating vector points representative of points on the image;

calculating information indicative of the quantity of nanomachines needed to create a holographic representation of the image;

calculating axis-specific vector data; and

transmitting vector data and nanomachine instruction data to a display device, wherein an electromagnetic field is generated from the transmitted vector and nanomachine instruction data.
