Available here. This is from an older, beta version of the project which has a few bugs but nothing too serious.
(YouTube video quality is rather meh, btw.)
I'm considering making the source-code for this project available if there is interest. Nothing too fancy or complicated, rather messy (I had to rush towards the end) but with a few interesting features nonetheless: z-only pass, blur, bloom, shadow, water and SSAO effects and an alpha (but quite extensive) version of an OO OpenGL wrapper.
The latter has been folded into the OpenTK demo project that I will be releasing shortly, alongside a few minor site updates.
