Anyone have reference on the holographic data chip from HALO?

Weta makes a figure of Cortana projecting from the chip so I have seen those photos. This is the chip that plugs into the back of MC's helmet. Does anyone have any other reference?

Thanks in advance.

I also saw a couple pics at the 405th.

Anybody know of any other info?
