The biggest problem with handwriting fonts is that they're easy to pick out as computerized when you see two of the same letters next to each other. Having just a subtle difference in the way the same letter is written helps trick the reader's mind into thinking that a line of text is ACTUALLY hand-lettered, when really it's not.
Getting back to my PROBLEM: Right now I have to manually differentiate between upper- and lowercase letters to make my fonts look authentic. Currently, "balLoOn" has to typed out by hand. That takes time. Time I don't have. So I was complaining to Mr. Stwalley about how I wished there was a simple Flash program to do the work for me.
So today he surprises me with "The Shanksizer" -- a fun and simple way to alternate your caps! Drop in a block of "normal" text, hit the fish, and out comes your text with alternating text! Of course, the best part is that it's a fun tool to play with even if you don't give a hoot about the problems associated with naturalized handwriting fonts. And if you hate fish.
Note: Concurrently, BTA and PUNY are working on a similar program aimed at professional letterers who deal with naturalized handwriting fonts on a daily basis.
