A few weeks ago someone asked how cranes can self build.  My neighbouring job is, as I type, building the next level of the crane.  The sections of tower are placed on the platform to the left of the tower and the tower is the jacked up so the next section can slide in.  You can see one piece about to be slid in and the next on the hook.

The first piece has been slid in and the crane is jacking itself up to take the second piece.

I need to have a word with myself because I thought this was cool.
