This perhaps doesn't need to be a feature request. I just wanted to bring some of the folks over here into the discussion happening in General Discussion:

Hey folks, I've used Sublime Text now for a little over a year, and I've always felt that the icon didn't really say a whole lot about what Sublime Text actually does. I've seen a lot of basic icons that show the letter, and a lot of copies of the button theme, and even a few that show markup.
For me I wanted to start with what Sublime Text means to me.
It's a building tool. It creates the foundation, and so I liked the idea of blocks, and I liked the idea of abstracting the "S" a little bit. So after a few months of dwelling on it, I felt inspired to take a crack at it and I'd like to submit it to everyone if you're interested.
I started with basic blocks, and refined through a number of steps.
and finally landed on something like this.
This icon has been saved out at HiDPI resolution as well. Mac only for now.

Enjoy, and feedback welcome of course. I'd love to take some ideas and run with them.
