What, who, where am I?!?
Craig Lotter is a web developer based in Gordon's Bay, South Africa, who seems completely incapable of shaking off that pesky inner child within, the one that forces him to love all things animated or hand drawn.
The Rugged Rock of Craig contains snippets of his life, popular culture and all the important things like anime, manga, games and comic books. The CodeUnit of Craig on the other hand contains the more serious stuff like code snippets and tutorials, while the House of C chronicles his foray into the world of web comics.
For which it never seems he has enough time anyway.
