In my opinion, I'd say your presets are simple, but they do still look good.
When I saw hypnosis, I was going to suggest more color control by a per point basis (in the superscope), but I found that you already know how to do so, after I saw purdy colors.
I find that the zoom/tunneling based presets are the easiest, yet also one of the best genre of effects to look at.
I tweaked your movement to:
bonus: r=r+0.1*sin(d*1.5-0.5) looks neat
The order that the movement and the superscope are in on the list also changes things; where having the movement after the superscope gives it a less pixelated look.
I wouldn't call my presets
anti-simplistic; I've seen some that delused my p3 933 system down to 15 fps at only 320x240. But, no harm in looking, especially when they are mine, eh?
Keep it up.
