I love irrlicht and now (finally) I love shaders...
I have posted a depth of field implementation based on Omer's work and some RenderMonkey examples.

I also have an update to Omer's HDR effects... I had to modify them significantly to get them working for my ATI card, but now they should be more generic. Also, I have updated his code for Irrlicht 1.2. Write me if you want this...
