I've just come across this trailer for the Gruber Ballet's unbelievable Alice. I say "unbelievable" because I can't believe human beings can do some of the things in this performance. Even though they are obviously professional gymnasts. See if you agree.

If you're interested in attending their performances in the near future, looks as if you'll have to go to France! However they are in Tel Aviv and Dublin in May, and having a Canadian tour in the autumn.
