I am working on a single eye HMD. It is 640x480, 47 degree field of view, has built in sound and mic and motion tracker. Using the frame of some glasses, no lenses.
i like the borg look. but it could be a cleaner borg look. namely no scotch tape. lotsa inputs, thats good. i dunno if gaming on it would be viable though, just because it is a monocle. the fact that it covers only one eye might pose issues.
