It's like hunting the Snark, beauty or butterflies. It takes a little practice. It's like an instrument. Or a game in which the goal is to experience color music and create visuals you like. Unlike most instruments, Aleph Null will play something whether a person is playing or not. But it benefits immensely by a human player. It knoweth not beauty, is but the instrument of thine own incandesence.
