The Ballerina and the Mirror

A few years ago someone showed me this short animation - from a Russian animator i then promptly lost the link to it  and  re-discovered it only  recently...

I think most dancers have had their moment when suddenly things  seem to happen  for no apparent reason...  you get caught up in the moment  and it all happens... I know I have -  it's just something  that happens sometimes, the  teacher, the pianist, other other dancers,  the  tides  and the stars  all align and  *boom* you have an magical class.
