@Claes Wallin (韋嘉誠) Yes, afaik it's the first example I know of it. The design came out of a conversation with Fateh of http://urchn.org/ fame (Bassam and Fateh of Urchn guided me greatly in the production of those animations, and Fateh also contributed a bunch of ideas to the second animation).

It's probably just zeitgeist, but I do feel like a lot of the ideas we put into the animation have become pretty common in the anti-surveillance materials that are out there. Shortly after the MediaGoblin video first came out, the Internet Defense League also used the "cat massacre" idea, though I think that idea could be easily reinvented.
