Apparently from the 7th – 25th of December you can enjoy 3 whole weeks of contact improvisation as part of Israel’s International Contact Improvisation festival. It starts with a week of residential workshops out of town, follows with a week in Tel Aviv and then goes on the road for what, frankly, sounds like a pretty magical week. You can join in on either one or all of those weeks and there are special offers for absolute beginners.
You can learn more about the festival on their website (in English).
And here’s what Wikipedia has to say about Contact Improvisation.
