Well, I should probably offer some test bed, huh? I guess this whole thing is more oriented to WoW players than anything. So I'm writing an addon called StarVisuals. It'll have AVS elements, and a scriptable image widget for drawing generic images.
Here's the project page if you're interested. You'll need to dig into the code to configure the superscope parameters. Currently there's no chaining render elements, and all that's available is superscope. I've started on Blur some.
Anyone play WoW? Want to draw something?
