please, someone confirm they are display cases! It would be nice to have the prototypes we’ve been working on there.

--------
Those prototypes would be too valuable to risk to theft or vandalism (at least the actual ones). Those should be shown in a guarded setting resembling the interior of a bank vault. I suppose they could build a model of the prototype for the public to gawk at, but it wouldn't be as sexy as (say) a replica or cutaway model of a fancy new automobile engine.
