Great! Would love it if I could drag any number up/down to change it and see the result in real time. Same thing for entering a new value: see the result as I type. Right now editing the value removes that block's effect, which makes it very hard to tweak and play.

Maybe check out vvvv[1] and the VL.Fuse[2/3] library for realtime node based shader programming.
