From the campaign:
Some rare matryoshkas - or Russian nesting dolls - ended up in the hands of various antique collectors. Sets of matryoshkas like that are worth a lot of money! These collectors arranged a meeting to exchange dolls to try and reassemble the rare matryoshkas. Each collector wants to leave the exchange with the most valuable collection. But who will succeed?
The Kickstarter campaign is running now. They're around 1/2 the way to their goal with still 12 days left to go.
