Drawings from Instrument Two drying after exposure. Also the photograms from the dioramascopes.
Instrument two shown below.
In terms of structuring ideas the optical bench lies between the ubiquity of scaffolding and the specificity of the armatures that hold dinosaur skeletons or the dynamic frames of planetary models (for example). They are content specific but allow that content to be played with.
The active pieces in the lower image are mute without the bench, which brings them into a negotiable relationship.
The VAB at Cape Canaveral is large. The side bays seen above in stereo have platforms to fit the lower stages of the Saturn Five rocket. We are still in the lower part of the building. From the outside (below) you cannot calibrate the scale, and it is hard to do so inside despite markers such as stairs and railings.
A similar view to the ones I posted the other day of Dungeness, but seen in stereo you can pick out the folds in the land that are hidden when viewed in 2D. The track was to carry fish from the boats to the road (see here for earlier post)
