There's a few ways to go about it. Either the screen will display the left and right images polarized simultaneously, and the polarized glasses will sort out which image goes to which eye. Or, the left and right images will be interleaved frame-by-frame, and shutters on the glasses will select which eye gets which image. The best option is no glasses. You know those holographic posters where the image changes as you walk by it? It's exactly like that only the image changes every 3 inches, so each eye is guaranteed a different image (only in this case it's not a movie poster, it's a movie).

Ocean-Crossing Dragonflies Discovered 95

grrlscientist writes "While living and working as a marine biologist in Maldives, Charles Anderson noticed sudden explosions of dragonflies at certain times of year. He explains how he carefully tracked the path of a plain, little dragonfly called the Globe Skimmer, Pantala flavescens, only to discover that it had the longest migratory journey of any insect in the world."

Just use an uninterrupted power supply system. It can be built to draw current only when the batteries are low, and that can be programmed in, so that the actual draw of electricity is orthogonal to the use of the electricity. Think kind of like a Prius.

This sounds like an energy-efficient design. Some else suggested a capacitor--that wouldn't be so bad, I suppose.
