David Hellman has put together a very nice collection of Braid graphics called the Braid Graphics Briefcase. This collection contains a bunch of icons you can use as forum avatars, or program launch icons, or … anything! It’s also got some screenshots and a giant desktop wallpaper. And more.
Here is a small taste of what’s available on that page:
This complete set includes all of the Xbox 360 Gamer Pics that shipped with the Xbox Live Arcade release of Braid, and many images that were not included in those. (For fans of the dinosaur, he’s included this time.)
