Make more 2D shader tutorials
Add more 2D shader tutorials. Things like glow and lightning, etc.
Pls do :D AND pls vote anyone :D
By the way, there's a start to this here: http://rbwhitaker.wikidot.com/post-processing-effects. I'll admit, it's a very long way away from glow and lightning.
Feel free to add suggestions for specific 2D shaders in a comment, if you vote for this idea!
