Erasing points us, as ever, to another Ouroboros: Check out a sample of the song of that same name by the Mars Volta.
Dizzyhead David sends us a clip of Bob Dylan (!), on his radio show, talking about famous examples of art- and breakthrough-inspiring dreams: "...And Friedrich August Kékulé, who was a remarkable figure in the history of organic chemistry—he once had a dream about a snake biting its own tail. From that dream he figured out the structure of Benzene. I would have just figured it was a sex dream or something." (E-mail me and I'll send you the clip.)
And finally, fans of the late Robert Jordan's Wheel of Time series know that the covers of these books feature Ourobori...in lemniscate form!
Coming soon: Ed shares/inflicts another of his motifs/obsessions with Dizzyheads...
