+      Flames are algorithmically generated images and animations. The software
+      was originally written in 1992 and released as open source, aka free
+      software. Over the years it has been greatly expanded, and is now widely
+      used to create art and special effects. The shape and color of each image
+      is specified by a long string of numbers - a genetic code of sorts.
