Indeed, thinking about obfuscations or ANYTHING 'interesting' (whose definition depends on the one doing the thinking, naturally) is orthogonal to getting to bed on time.

Conversely, it seems I don't tend to come up with anything interesting UNLESS I'm currently past "bedtime"... You should've seen how late I was burning the midnight oil for Breaking the indecipherable cipher, courtesy Charles Babbage.. Well, I guess it shows how late in the node :)
