- The Many Lives of Null Island (stamen.com)
At risk of ruining the secret for you, Null Island is a long-running inside joke among cartographers. It is an imaginary island located at a real place: the coordinates of 0º latitude and 0º longitude, a location in the Atlantic Ocean off the coast of Africa where the Prime Meridian meets the Equator, hundreds of miles from any real dry land.
- Triband (flag) (Wikipedia)
A triband is a vexillological style which consists of three stripes arranged to form a flag. These stripes may be two or three colours, and may be charged with an emblem in the middle stripe. All tricolour flags are tribands, but not all tribands are tricolour flags, which requires three unique colours.
