We are in the Uru expansion pack at hydro power plant approached via
the monorail car. Please answer the following questions with either
"yes", "no",
"difficult to answer with a yes/no" or "don't know" only!

Q1: In the four scope room, there are three gauges in each scope. The
middle gauge symbol seems to represent some balance weights. Does this
gauge actually control a real set of balance weights some place in the
game that we can physically see? Yes/No

Q2: In the four scope room, the right-hand gauge seems to control the
red-blue ring to the right-hand side of the gauges. We have been able
to get the red-blue ring to rotate on each scope, but we don't know yet
what the red-blue ring controls. Does movement of the red-blue ring in
a scope actually control something somewhere in the game that has the
colors red/blue associated with it? Yes/No

Thanks in advance for any help you can offer.
