In anticipation of the Idea Book's release, I would like to point you to a couple of resources I've created for the robot I designed for the book.
My robot is called 3DPhotoBot and it will allow you to create 3D images using a single digital camera (a standard film camera will work, but requires the extra steps of developing the images, including one in reverse).
I'm making available a tutorial on how to use the robot in both Flash and QuickTime formats. Just download the one you want and double-click it to run. Both are zipped files and are less than 2.5MB in size.
When the book is released, I would like to ask a favor from those who choose to build the robot - if you've got a 3D image that you're extremely proud of, please send me either the Left and Right images OR the red/blue anaglyph image (see the tutorial for an explanation). I'm going to have a webpage created where we can share and display these 3D images.
(The tutorials are identical, so just pick the one that works best for you.)
