Holger Krapp gave a great presentation on flying insect vision cells and their sensitivity to optic field flows. Don't know if you have any interest, but it's pretty elegant.
I don't have a link to the seminar (I should check - there's a chance it exists? This was hastily scrawled to my phone during the seminar) more a heads up that this research exists and I thought might be of interest in terms of computer vision.
