# Sean Clemmer                                                     Why the QR code?
# Basically cause I don't like it.                                 It's a token, like all physical art in a way
# It's obscure and immutable and insensitive and secretive.        It's the leftovers you ant
# But also well-formed and regular and geeky.                      Cause the "real thing" is gone.
# A QR code is just a two-dimensional bar code                     But it's a token that explicitly
# it has some neat stuff like error detection and speed            directs its viewers, and that's a powerful tool
# it doesn't store all that much data--mostly we encounter links   Because I'm nosy and human
# URLs, pointers, addresses, identifiers                           and yeah I wanna see what people do
# {PRAGMA INSERT QUOTE                                             and yeah also change them
