How did they do that?
The skaters' configurations shift as quickly and seamlessly as a kaleidoscope. Four groups of four skaters arm in arm morph into two lines of eight skaters arms across shoulders, morphing into a circle turning counterclockwise, morphing into a whip of skaters spinning out of the circle, morphing into pairs of skaters holding hands. Often, parallel lines of skaters will intersect--letting go of one another's shoulders right before impact--turn, and suddenly be in a completely new grouping.
Wait. How did they just do that? I cannot differentiate individual skaters, I only see the formations they create. The velocity at which they skate but do not crash and do not fall is mind-numbing. What coordination and courage this takes! I cannot take my eyes off the ice.
The two long tables of judges give the competition a gravitas that should not be missed, but it is the cheers of the crowd (mostly skaters) that let you know which moves were particularly impressive.
