just wondering about the technic you used to animate your sig?
no airbrush or smudging.
hmm..hope this isn't too confusing..
The oval animated area is a layerset containing 10 (ten frames in this case because of the looping) nudged frames of vertical white lines which each has applied a displacement map which is a seperate b/w copy of the center oval area applied with a subtle blur. Each line layer have the filter:wind applied for the shimmer effect.
This layerset can then have different blendmodes for different effects. On top of the layerset there's a b/w gradient map that again can be set to the different blend modes you have in PS.
On top of all that there's a highlight 'glass' layer as touch up effect.
An oval layermask was then applied to the layerset containing the lines to mask out the anim.
that's basically it.
The important part is to use displacement maps so the anims aren't flat, but follow the curves of your shape.
The attached image is the old 'simple' version of my sig - it shows better what's going on.
You just made me make meself an avatar! lol
