hey Tom, great viewer, congratulations!

I played with it a little bit and it does an ugly distorsion of the equirectangular image at the nadir (and probably also at the zenith). I guess it has to do with the OpenGL geometry. how about transforming an equirect into cubefaces first, and use them for display?
