Subject: [alt-beam] Re: Ant vision
The landmark recognition could probably be done with a vision circuit I
recently saw posted to the list. polarization??? Interesting, and the
dinstance registering. I saw that show. Forgot about it, but it was
quite amazing!

The lover part of the ants eyes looks at the ground and registers distance travelled. The middle part checks the horizon for landmarks. And the upper part , and this is the neat thing, can actually see the polarization of the sunlight as a grid on the sky. The ant uses this as compass, taking into consideration the time of the day.
