There's a merry little club called the "Best Friends Forever Club". And, although they consider themselves to be very enlightened, they love to death gathering around their favorite place on Earth: a shady little cave.

The reflection of a tough game
Just an endless constellation of dully twinkling lights:
played on a grid ...
... and encouraged by an evil little bird.
