Internet spam is an overwhelming disease of the 21st century. With very elaborate devices, we go to great length to avoid seeing spam: junk-mail filters, screening services, spam databases. SP4M attempts to turn the relationship we have with spam around. A microcontroller-based Webserver retrieves spam sent over the Internet in real time, and remotely feeds a continuous shuffled stream of it to public displays. Spam is no longer meaningless, time-consuming junk, but rather a diagnosis of cultural values and an alternate representation of societies.
