Like benign triffids, box cranes proliferate within the prosperous patch of land that is Munich.
When I notice one being constructed, I watch with awe at the apparent ease it is assembled, within a few hours.
Because so many cranes are being used I think that they are running out of complete sets with the same colour scheme. A recent unit displayed a range of colours for its various components, like several different editions of Meccano pulled from the bottom of the toy box.
Ah well, everything appears orderly and working despite being cobbled together ... unlike Brexit ... !
