First off, thank you to all the MOOsters who participated in last week's challenge. As always everyone who took part kept us entertained with their creative, logical and in other cases wacky answers to our question. Just to recap the challenge, I was looking for an answer to how many combinations one could arrange 20 MiniCards in the Mosaic Frame. While there is probably a correct mathematical answer out there, all the answers were inventive and thoughtful and worthy of recognition. There is one honourable mention.

The honourable mention goes to Rob. He said that the answer is only one. He believes there is only one combination that will look perfect. I like the idea of perfection and I can't wait to see Rob's creation. Congratulations to Rob who wins a pack of MOO MiniCards.

And now to our winner. Drum roll please. The winning answer is the Mosaic Frame can be arranged in 72,130,678,738,421,022,720,000 different combinations according to David. While I am still not 100% sure this calculation is correct, I had enough math geeks concur that it probably is the right answer. Hat's off to David who really wowed me with his explanation. As the winner of the challenge David wins a Mosaic Frame. Congratulations David, good luck in testing out your theory.

Happy Monday!
