In 1948, the Russian dance troupe Berezka formed, taking its name from the Russian word for birch tree. Audiences were mesmerized by its special step, hidden beneath the dancers' long, flowing dresses. They appear to actually float over the floor! Skip to about 1:30 in the video to see this effect.

"He [Terry Nation] was also inspired by a performance by the Georgian National Ballet, in which dancers in long skirts appeared to glide across the stage"
