With the ideas of a proper Smilebox® (but a "proper" one would no longer be Smilebox®), and stereoscopic 3D viewing, and an "in theatre" experience, I looked around for a good, and cheap (free?), and easy to use, and continuously interactive, and powerful 3D program. I know, I'm an optimist. Fortunately, optimism pays off and I came across the once awesome program from Caligari, sold to Microsoft for their Virtual Earth online program, later discontinued by Microsoft when it moved on, and now freeware with the blessing of both the original author and Microsoft. How's that for optimism? Sometimes I amaze even myself. :D

It'll probably be quite some time before I could get around to this. So anyone with an inclination towards 3D design and rendering might like to give it a shot. Start at the Flat2D website to get the now completely free program with links to more resources (tutorials, plug-ins, and such):

trueSpace 7.61 is a powerful 3D modeling and animation [program], with several years of tradition. Its first version was launched in 1994, and the program has been refined over time, slowly becoming one of the most respectable of its area. In 2008, the production company was acquired by Microsoft, and then the software is now distributed free.

Start at United3DArtists forum's "Links that you might need one day using TrueSpace" and trueSpace:
