this makes an interesting reading, may give people some ideas..

That is the patent that the Headplay uses. It is interesting, but not really suitable for the kind of stuff we are making.

can you give me some more info palmer ,ive been looking around for a diy hmd and still not sure what the best way round to go debating on single display similar to what you have done , or twin displays mirror no mirror ,fresnels leep optics ,its all abit confusing which way to go, also its ni on impossible to get leep optics anywhere no one seems to sell anything similar very frustrating..

ps have also been looking at pico laser projectors because they never go out of focus so you can have a curved suface then maybe put right with warpilizer software thew my brain hurts
