Friend of the site Matt Parker recently made headlines because of his UK Government Petition to correct the heinous geometrical oddity that is the UK Tourist sign for a football ground. In the standard sign, somehow a sheet of tessellating hexagons is depicted as wrapping around a sphere in a highly improbable (and provably impossible) way.
The petition has achieved a modicum of success, in that it’s passed the 10,000 signatures required to elicit a response from the government. Sadly, the response isn’t quite what you’d like to hear.
