The Smalltalk Amber JS framework got some indirect PR it seems:

But the similarity of the name and difference in concept and goals led to some confusion in forums and other discussion venues and so the developers decided to rename SproutCore 2.0 as Amber.js. This was, though, a short lived move, as it was pointed out that Amber is also the name of a Smalltalk implementation that runs on JavaScript. The developers decided to change name again to avoid even more confusion and have now settled on the name Ember. A project site is now online with examples of bindings, computed properties, autoupdating templates and other features of Ember.js

via SproutCore 2.0 becomes Ember.js – The H Open Source: News and Features.
