I've been going through and detailing every rig for each gag in the film. In total, there are 11 gags, with about 15 rigs. Here's the diagram and rough storyboard for the 'Monitor Explodes' rig.
It is written in shorthand, but the gist of it is that the sugar glass will be the screen and the 'explosion' will be a grip with a slingshot and circuit board pieces. This shot became four times as complex when I decided to put the 'shelf falls' gag in the same shot. That will take some rehearsing.
