Apparently some folks on some strange forum-like site have been wondering how the CRT effect works. Next time you should write a comment to the entry instead of relying on me watching site traffic analysis.
Anyway. I have prepared a stripped down version of the code and it should be simple enough for anybody competent to replicate the effect in his own code. As the ReadMe file says, the shaders are not optimized in any way whatsoever. Some of them are written in a blatantly bad way. But it's a good starting point for anyone interested.
