"The datastream will include a specially designed primer, or set of simple scientific principles and data that would be common to all extraterrestrial intelligences, providing a common base of reference to enable those receiving the signal to commence the mammoth task of decoding the encyclopedia. /The message will be accompanied by a short video message by Wikipedia co-founder Jimmy Wales, and images required for the re-creation of fundraiser banners/" (emphasis mine) Seems like they're very serious about their banners, glad that gift to the world has a chance of living on in the lives of extraterrestrials in the case of our inevitable demise!
