What a fun project!
We took a standard BuddyPress installation, and built a custom plugin that generates word games employing sacred geometric and CSS into a design known as the Flower of Life.
Each user can post a word that corresponds to other words (along with an optional description).
The utility has been in development for some time, and has experienced some delays, but is still going strong.
