I love the new design and I'm eager to brandish a Stack Exchange t-shirt at Dreamforce, where do I signup for the goods?
Awesome stuff, was going to ask if I could get a t-shirt to wear for my Salesforce StackExchange session at DF with Matt Bingham!
If it's amenable to the StackExchange team it'd be great to get some extras to give away at the talk, so you might be able to get some there.
+1 - I too have a session focused around community learning on Salesforce at Dreamforce 2014 (precisely on the opening day of the conference - 13th October) and Salesforce StackExchange will be a key part of it. Hope to get one in time for the conference.
There are several sites on the web, where you can create/design your own shirts.
Only problem, is that you need to have the rights to use the design.
I don't think we have these rights.
I did play with one (made an iphone 5 case :-) )
Another site is www.zazzle.com
If we can use the images, that will be awsome.
