Work with schools, government, and the public which started as a grassroots movement that is now global and a socially conscious business. Like the color purple.  Perhaps a hopscotch with a global/universal aspect. There is a 'Play Sign' that is two index fingers pointed up together making what looks like an eleven which also means 'together' in sign language
Staying away from the "kids" feel as it is aimed at Teens, tween, and adults. Welcome to check out @helpthe11th for the 'play Sign' 
There is a new website being designed and like to have a fresh start. 
Also, inducting 11 million PLAY NINJAs worldwide and perhaps that can be involved.  Not attached to any of these except for the color purple and a playful non-kiddo feel :)

Karjen was very helpful and made all the changes I requested in a very timely manner. Thanks so much... I am so happy with the outcome.
