Other than being the title of the Grateful Dead’s 3rd album, it was adopted by an early generation of hardcore kiters (particularly Dean Jordan) to describe a sense, a state of mind, or way of being.
On August 1st 1995 Andrew Beattie wrote a few lines about the kiting point of view of the AoxomoxoA on the Usenet newsgroup rec.kites:
If you fly stunt kites to win competitions, you won’t understand, but if you fly to give pleasure and entertain the audience, you might find AoxomoxoA
If you wouldn’t lend your kite to a stranger, you wouldn’t understand, but if you’re ready to loose or destroy anything you fly, you might find AoxomoxoA
If tangled lines are an irritating frustration, you won’t understand, but if you find untangling relaxing and therapeutic, you might find AoxomoxoA
If you enjoy buzzing noisy stunters on the beach, you wouldn’t understand, but if you’ve found the pleasure of a simple, reliable single-line delta, you might find AoxomoxoA
I found AoxomoxoA yesterday…
