Spot the Rivet!

At the end of the working day I was trying to get some inspiration from blipping our new building going up but all the tonka toys were being put away for the night. Just happened to glance through a side window and spotted these two guys carefully placing a girder into the structure. The guy on the left then started chucking rivets (?) to his mate with pinpoint accuracy. If you zoom in you can see the flying rivet directly above the guy in the cab of the crane (ah.. bet you didn't spot him!?)
