   My favourite @revisionparty trivia:

   [EDIT: Needs more digging! See: https://chaos.social/@dojoe/114404052729125609]

   The logo is a circular barcode encoding a 40-bit value; a unique ID that the 'ShotCode' web service rerouted to a destination URL

   This service and host website are well defunct (last active: 2007)

   The Revision logo is a cryptic artifact, reproduced in many digital releases from the party, absent of this context.
   A mystery in the demoscene archives that will await future historians.

     - Another circular barcode from the SpotCode group with specs: https://anil.recoil.org/papers/2005-mc2r-bluespot.pdf
     - Counting the example image on the Wikipedia page for ShotCode implies two rings of 24 sectors each which would make sense for 40 bits plus some sync and checksum

     I'm not sure that's entirely accurate though: The bullseye is not intact and there's many more than the two data rings required for a ShotCode. Also the sector and ring borders are inconsistent and not lining up in a lot of places.
     To me it looks like an artistic rendering inspired by one of the several similar but incompatible circular barcode schemes circulating in the 2000s.
     It might well be encoding some hidden message but I'm certain it's not a ShotCode :)
