Saturn's hexagon change in season. These changes were observed by the Cassini spacecraft. One hypothesis, developed at Oxford University, is that the hexagon forms where there is a steep latitudinal gradient in the speed of the atmospheric winds in Saturn's atmosphere. Similar regular shapes were created in the laboratory when a circular tank of liquid was rotated at different speeds at its centre and periphery. The most common shape was six sided, but shapes with three to eight sides were also produced. The shapes form in an area of turbulent flow between the two different rotating fluid bodies with dissimilar speeds. A
Hexagon Sun it is simply a title for the band's recording studio. It is believed by their fans that Hexagon Sun has held parties in the past, which may be how the collective originally formed. These get-togethers were soon known as "Redmoon" events, after the occurrence during one such party of a lunar eclipse which colors the moon red.. Hexagon Sun's presence on the Internet has been limited to its website, hexagonsun.com, which until 2005 when it redirected to boardsofcanada.com, was simply a small graphic of mirrored turquoise-color text on a blue background. When reflected, the text reads "the internet is evil.
