  • The uniform numbers in American football are unusual compared to those in any other sport. They are displayed in more locations on the uniform than in those of other sports (on both the front and back of the jersey, on both shoulders, and often on the helmet), and on the front of the jersey, they are displayed very large, taking up almost the entire front of the jersey. Just as importantly, certain numbers may only be worn by players playing particular positions; thus the jersey numbers assist the officials in determining possible illegal actions by players.

  • Most people are repulsed by mould, but one artist is using it to create creepy, decaying architectural models of houses.

    Daniele Del Nero creates architectural scale models of buildings with a domestic look to them. He then dampens the exterior of the structure and applies a thin dusting of flour. The model is then placed into a transparent plexiglass case. Mould starts to grow after a couple of days and dies within two weeks, leaving behind what Del Nero describes as "a dusty spider-web which covers the model like a rambler plant".
