Here are apps that play with words and with dimensions, but most of all they play with patterns of 1's and 0's, building worlds from the white and black squares of randomized chessboards. In these chessboard worlds you will encounter characters from the Galactic Mindsea Empire. The White Stallion of Mars and the wild black mare Ahaha are all 1's and all 0's respectively. Together they give rise to all the horses in the empire.
