djinni (formerly known on LJ as ninjahijinx) periodically does a "free icon" day, with an open paypal button for donations, and a limit as to how many free drawings he will do unless a specific goal is reached. Recently, he offered to do an icon or a dragon, and if you wanted a dragon, you gave him three words as a prompt. The prompts for this dragon were storm, rage, and rainbow. Isn't it cool?
Oh, and he also did my musical kitty icon.
He's also doing a Dracula comic, and periodically shares other art on his LJ. Go check him out!
