37signals has set up a flickr stream showing screenshots of various UIs, most of which are Web-related (tag: screensaroundtown). There are some nice components in there, though some of the shots don’t seem to fit the group, like the install window for Adium.
I like the concept for its simplicity of purpose and implementation – it’s a refreshing break from the large sites that gather cool designs from around the Web.
