An anonymous reader writes "A new cracking contest to cryptanalyse a William Gibson poem. The electronic poem ('Agrippa') was written back in 1992 and self-encrypts after being displayed once. The person who successfully cracks the encryption will win a copy of every published Gibson book."
The poem/program binary was recovered in 2008, but it looks like no one has managed (bothered?) to crack the code.
If it happens once, it's a bug. If it happens twice, it's a feature.
If it happens more than twice, it's a design philosophy.
