From an Hourglass.
The Circulate path of an Hourglass consists of 8 spots.
Move forward to the next position in the Hourglass, moving from a Diamond position
to a Box position or vice-versa. Change your facing direction (by 90°) if and
only if you are moving to or from the Point of the Center Diamond.
If the Circulate does not involve dancers ending on the same spot, then
ends in an Hourglass. EN: 377
