Textmate alternative icon by vladstudio:
I really wanted TextMate icon to be book, not list (to represent projects, not files). Made in Photoshop. Enjoy! :-)

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.
What about Wolfgang Bartelme's alternative versions] to Jon's icons?
I think, they're a nice improvement and a good example of open development, i.e. one building on another's ideas. Kudos to Jon and Wolfgang!
Update (2005-07-08): This is now (and has been for some time) the new official icon. Wolfgang has provided me with the PSD for the image in various sizes and one big size. -- Allan Odgaard
