A little "wearable" video camera that continually captures the last 30 seconds of whatever you (it) are seeing. It looks like the guts of, or at least the same manufacture, of the X-10 spy camera.[boingboing]
I mounted an x10 camera on Zeke once just see what he did when he was outside by himself. It was attached to his doggy-backpack, which meant that it didn't really see what he was looking at, just the same general direction. I need to modify the camera so I can mount the lens on his head (he'll love that), with the battery and antenna in the backpack. Dog immersion video. Might be a little hard to watch, especially on a woods hike.
Most of Zeke's videos would be pretty boring...him sitting on the porch looking inside to see what we are doing. The video I want is what our cat does outside all day.
