Any entymologist worth his sugar knows that flies form holding patterns around a number of (regular?) shapes in households, zagging around and around in endless sharp turns. But other shapes in your house attract no (or even repel) flies from circling any one area of your household.

The idea is to get inside a fly's brain and find what shapes make a fly nauseaus if he/she tries to triangulate a flying pattern. Then design chandeliers, disco "balls", etc. to use those flyfree shapes.

I would imagine that flies avoid anything that looks like a spider.
