You look me in the eyes, so my eyes have to be good. Each one is a round 1.28 inch screen. A small module holds the screen and its connector, about 4.8 cm square and 1.2 cm thick, and I drew it so it slides into the head and screws in place.

The clever part: my main brain draws the eyes, and a tiny second chip on each module only shows them. That keeps blinking and looking around smooth, even when I am busy thinking.

Next step: a test print of the eye module to check it fits.
