Mummenschanz mime troupe

Above are the Mummenschanz mime troupe who I'd never heard of till today, although they've been around since the seventies and are still performing. This is a clip from the Muppet Show they were on. The control they have of the clay is brilliant, I say clay but I've no idea what the stuff is. I've never come across clay like it, more like a cross between dough and bluetack.
Anyway whatever it is, they're amazing with it. I mean they're doing all that modeling without being able to see what they're doing. I'd love to have a go!
You can read all about them on their

and see a few snippets of other work they've done.
