True story: the Cambridge Maths Society, The Archimedeans, had a journal called Eureka (of course). It happily published interesting but not important bits of mathematics. One student wrote a proof of an impossible sequence for any width board. It's even impossible if you have perfect knowledge of the sequence. All you need is to drop Ss and Zs in an irrational order.
I think this got published in 1990, but I can find little evidence even if the journal's existence online.
