Well I do have Photoshop, and I just tried. I used +500 to twirl it

What happens when you reverse twirl the

No, I tried several times and it was just a mess - nothing
recognizable. I suspect that the untwirling is very sensitive to
circle center location and radius. When I first did it in Photoshop,
I just left the ROI in the exact same place, so it was able to do a
very good job de-screwing the image. With an arbitrary photo you're
just guessing. I guess I guessed wrong and it wasn't able to
restore. I imagine you'd have to iterate trying all reasonable
locations for the center of the circle and radius of the circle and
see which one looks best. Even after that, it may need some manual
artistic retouching.
