I photograph grasses and have taken quite a few beam-splitter 3d photos 
that way. But you won't be able to get as close as you want. By the time 
you get to 18" there's almost nothing left in common between the two 
sides of the frames. 

Although I've never actually gotten in touch with him, Marshall Enquist, 
the author of _Wildflowers of the Texas Hill Country_, Austin, TX, Lone 
Star Botanical, 1987, took every single photograph in this book in 
stereo. As I understand it, he collected the flower, then ran (not 
jogged) back to his van where he had a small studio set up for the 
purpose. The pictures were all taken with flash (black background) and 
are excellent! I'd love to see them in 3D.

Perhaps you could find him in the internet white pages -- he might be 
able to help.
