Tech Tower is the inspiration for the clock case.  Early 2D and 3D modeling efforts are shown. Note that the pendulum and the full height of the clock case are not yet included.
This is a first full height view of the intended clock.  Compared to the prior images, the scale of the case is shrunk to 75% so the escape wheel pallets are centered in the arch window behind the TECH lettering.  The clock dial is at 64" up from the floor.  The peak of the roof is at 108" (9-feet).  Note this view shows using the image of the GT seal on the swinging pendulum bob.
