This plugin applies a `point warp' at a given location on the image. It's basically bulge [ :Bulge: ] but in the horizontal plane instead of the vertical.
The UI (v1.1) -
I'm not truly sure of the uses for it, but it's interesting at best what can be done with it. Completely based on the Gaussian function and nothing more or less.
Made with the v3.20 UI.
DLL and source (both ZIP'd) attached.
Edit: After figuring out what I actually meant when I wrote the base of this code back in April, I made some small modifications to the UI and code that should look and work with more intuitivity. (v1.1 minor)
