This month's (Aug 2018) Computing Edge magazine (a professional journal from the IEEE) has a wonderful illustration of Alice and Bob in an article on secure communications. It's Alice from Alice in Wonderland talking on her smartphone to BOB from Twin Peaks. The references tickle me so much -- and are so troptastic -- that I want to scan it and replace the image we're currently using.
Topic on Talk:Alice and Bob
And I finally got around to uploading the scan I made months and months ago. It's now the new page image. I left the markup for the original image in the page, commented out, if anyone wants to swap them back.
