Email Addresses 
Neal R. Wagner

Please use the "gmail.com" account below, rather than the "utsa.edu" account.

The GIF images below give several ways to hide my old (still valid) email address in the first, second, and third images, as well my new one, in the first, third, and fourth images.

These illustrate ways to use "messed up" GIFs to try to keep web crawlers from getting these addresses.

First, add "noise" and straight lines.

Second, similar, but extra noise letters, and rotated, tilted

Third, add black-white reversing circles.

Fourth, hidden in stereograms (see Autostereogram, Stereogram)
pretty hard to read! (constructed from stereogram generator)
