It's not quite on the level of embedding images in a spectrogram, but buried deep in Amarok by Mike Oldfield is morse code for "FUCK OFF RB", a reference to Richard Branson, owner of his label, Virgin Records.
As far as I know the only developer on the core team with a kid is Adam Saltsman, and his kid was born in 2011. I think all of the team members are young enough that they would have been teen parents (12-16) if they had kids born in 2003 or 2005 :).
I saw "Indie Game The Movie" last night (http://www.indiegamethemovie.com/). They followed the ups and downs of developing fez and super meat boy (and some braid).
If you're racing to develop something before you run out of money, take a break and go see this movie. You'll love it.
