I'm looking for a site that is basically a collection of Twitter profile pictures. You sign up for the service and in doing so, authorize others to use your Twitter profile picture for their projects (e.g. say, as a dummy user in their app). I think the license was for personal projects but it has an option for commercial projects as well.<p>I vaguely remember seeing such a site (on HN?) once upon a time ago but I can't seem to find it. Does anyone know what I'm talking about?<p>(I'm using it to build screenshots for an app.)
