So here's the first post.
This is an anaglyph - 3d graphic - requiring Red/Blue glasses.
At least I'm pretty sure Red/Cyan won't work,
and I'm absolutely sure that the polarized 3d glasses won't work.
The free VRML rendering software (plug-in) that I downloaded, Bitmanagement Contact, provides the option to walk around in the VRML scenes I build in anaglyph mode.
