Joshua Emmons's first stab: I love everything about TextMate except the icon. It looks too much like a document (as opposed to an application). I agree with dan del piano all those here who are in support of gears and the color purple. Purple gears are rad.
Made in Illustrator, and thus can take on arbitrary size upon request. Looking forward to your comments.
