So far, have the eye design pretty much modeled, just need to correct one error involving the rotational axis of several sections being incorrect, to which I'm waiting on a response from Matt with an explanation on how to do that since it's not working the way I expected.
Anyways! Here's a quick video of the iris design in action, followed by a semi transparent render to show the completed housing assembly.
The way this's set up, the iris blades can close in a circular pattern, similar to a camera iris, or the iris of the stargate in SG-1. Same concept and looks nice, while leaving a gap to allow the inner 'pupil' to see.
The iris is mounted on a gyroscope which allows it to rotate vertically and horizontally, with small gears to turn the gyros.
Furthermore, the 'pupil', is a mechanical construct of 4 cameras; infrared in the center, for primary vision capabilities, with smaller red/green/blue cameras around the central section which provide secondary inputs so that things which are cold or heat shielded don't go invisible.
The pupil can also rotate slightly in relation to the iris assembly, to give the impression of an eye looking around.
Behind the pupil and iris assembly, is a reflective surface which allows light to be reflected back, vaguely similar to a cats' eye, for adequate night vision.
It's pretty complex overall, but the rigging honestly shouldn't be that bad, and it'll be wonderful for a nice closeup shot.
