Luke always goes to bed with his head at this end of the crib:
The past few mornings, when he wakes up he's more in a diagonal:
And this morning our little wiggle worm has his body turned 180 degrees! (I actually woke up at one point and saw him in the video monitor - at that point he was laying cross ways in the bed.)
The funny part is that just yesterday we were commenting on how we want to start laying him in the bed that way so that he'd work on turning his head to the left and not always the right. I guess he decided to do it on his own!
