Not to mention the "...millions of shiny, circular plastic disks, 14 flids in diameter, with a 1.3 flid central hole. Most are found in rectangular display cases, which hold a single disk, though some cases hold two, or even three disks. Some are blank on both sides, though most have undecipherable patterns applied on one side. A very few have what appear to be representational art work on one side. All have at least one side blank.
Mainstream xenoethnographers believe these are ritualistic items; some radical iconoclasts speculate, that they are a form of currency. A few untrained popular sensationalists, such as Von Lokigan, make unsupported claims that they are an unknown form of data storage device."
