Progress on AstroObserver for Android

I've been learning OpenGL ES 1.0. Here's what I'm getting as a full-sky star map. It looks a brighter and better on my device than on this laptop, though--different gamma settings, I suppose.

I'm modeling the light flux pretty precisely: in other words, I scale the star by a factor proportional to 2.512^(-mag/2) (the 1/2 is there because the light flux is proportional to the square of the radius of a two-dimensional image).

If anybody wants to try the demo (which just shows a rotating sky at maximum speed), it's here.
