User Experience Q&A website logo

UX Exchange

I'm Matt Goddard, I've started a user experience Q&A website (UXExchange.com) based upon StackOverflow.com and am looking for a logo to use.

UXExchange is a free UX Professional Q&A site but i want it to look professional. I intend the logo design to influence the accent colours of the templates site.

The philosophy behind UXExchange is a labour of love for me. I'm passionate about spreading knowledge about user experience, usability, accessibility, information architecture. I believe it should be open to all.

User experience community

I would like a website logo and favicon that can be used on UXExchange.com

Dimension:

Logo: 250px X 56px
Favicon: 35px X 35px

I would like the logo to contain an icon (perhaps this can be used for the favicon) and the site name.

The icon should embody user experience perhaps taking influence form JJG's Elements of the user experience diagram (a google search should bring it up).

However, I'm open to any good suggestion and good designs.
