There's no real reason to pull the foam off the inside of the back case, but this is a teardown, so we're doing it.

We suspect that the foam is there to provide a flat, even surface for the LCD glass to brace against. But there is one thing that we do know about it: it is super sticky.

The bottom edge of the case has two features that we found pretty neat: a laser engraved data matrix code and a nifty arrangement of round indentations.

Upon further inspection and with the help of some keen-eyed readers, it appears that those dots form the pattern of a glider from Conway's Game of Life, the universal symbol for hackers.

That sixth dot to the right, though? Apparently, if you were to place that dot while playing, it would place the entire game in a state of death. Is Apple trying to send us a message?
