[Edu-sig] 3d goggles -- any recommendations

[Hans Fangohr]

Dear all,

I am looking for a product that provides three-dimensionality to OpenGL 
(aiming for visual Python but also VTK graphics) scenes (for teaching 
purposes). Something like graphics adapter with 3d goggles which work in 
sync and provide two pictures one for the left and the other for the right 
eye. Price range not to exceed 250US$; better less.

Does a product fitting this criteria exists? Does anyone have any 
experience with such systems?

Thanks,

Hans

P.S. It would help if this piece of hardware worked on Linux.
