I’m a big fan of public transportation and love reading everything about HTM trams, so I just had to share the photo I made about the check-in/check-out machine in one of the local trams:

For years these machines display gibberish about 50% of the time. The machine should read IN/UIT- CHECKEN at this moment, which it… mostly… does. But about 15 seconds prior ‘CHECKEN’ was actually ‘SLURKEN’. I’m not sure why exactly, but one letter randomly changes here and there and random symbols appear on the sides.
Maybe it’s all just a big puzzle we are supposed to figure out.
