I'm planning on building and releasing a suite of Construct Effects (Shaders) over the next little while.
I still have a fair bit of work to go, but with luck I'll be releasing an alpha version of the set shortly. At this point, I mainly need to finish off a few more Effects, and then fill in the documentation for the parameters and such.
Presently I have a little over 20, Effects, ranging from tone manipulations like soft threshold, bias, and gain, to more special case effects like a fairly flexible scan line generator.
Once the first version is released, if anyone is interested in testing out the effects in that alpha version and giving me feedback on things I might need to fix and the like, any such help would be much appreciated. :)
Anyway, I'm hoping to release the first alpha-ish version of the actual .fx files in the next few days. I also want to put together some interactive visual demos of the Effects, but I'll probably start doing most of that after the first alpha release.
I did build a demo for the "Bias Gain" Effect, just to kind of rough out the style I'll probably use for the other demos. You can get a copy of the compiled demo from the link below, to get an idea of the kind of stuff I'm working towards. If you have time, let me know what you think. :)

(I'm interested in making the demo apps resizable eventually, but the prototype at the link above has a fixed size of 1024x768.)
