I've been building this thing for quite some time. For the last 2 nights or so, I spent some time finishing up version 1. It is now functional. (and has taken 23 or so pictures of my desk plant in the last couple hours)
Photos of the rig (with notes pointing out the parts) can be found here: http://www.flickr.com/photos/abandc/sets/72157600201419395/
When I get the pics parsed into some useable video, I'll post it here. Today is pretty much a proof of concept day, then I'm going to find a way to position it, and light a plant such that I can get pics of Celeste's blooming Christmas cactus.
