Here's a rewritten and expanded version of the article on the Warp Entity tool I posted on July 19. This version contains a lot more information on how to use the tool, plus a good many more example applications. I think it's easier to read than the first version, too. Fifty-four pages, 47 illustrations.
If you had downloaded that first version, download this one and trash the original. If you don't have that one, and Warp Entity looks like it might be interesting, try this version.
P.S. 03 Oct 2016: Just corrected a couple of typos (pp 3 &7)and uploaded the newer version. I'll be grateful to anyone who points out more typos or other errors.
