Emergency blip #2 - losing my marbles

Marbles:
A traditional game played throughout Lent (please note I'm not religious but this is an emergency). The game has been played for hundreds of years and some historians say it might have been started by rolling eggs. In the past round stones, hazelnuts, round balls of baked clay and even cherry stones have been used.

I would now like to direct you to a link about motivating marbles which I find very inspiring and hopefully you will too.
