As of now, the effect I am attempting to achieve is "unsteady". I also was thinking about "protuberance" (probably not a word), "deformed", and "agitated". If any of these make more sense that "unsteady" or if you have any other ideas that would be extremely helpful.
The "unsteady" effect is manifesting itself through the slight bends of the plastic as it is pounded out as well as the bow that will form in the plastic when is is hung in the curtain wall.
If anyone has any other ways to speed up the process of hitting each of these dimples one by one, that is probably my biggest concern right now.
(sorry for the bad images/backgrounds, I will put better ones up soon)
