Nice. Writing code is very different. People mostly seem to train English word-lists to increase wpm. But for code you constantly have to deal with new words, prefixes and special characters. Awkwardly placed special characters on the keyboard can ruin the flow. Dvorak, Colemak don't have any improvements over Qwerty - so they're most likely pretty useless.

Layouts with nicely placed special characters are all very non-standard. Building a custom keyboard nowadays is quite easy, but it takes some courage to train something that is seriously less standard than Dvorak ever was.
