AbstractAn Apparatus For Use With A Source Of Light Including A First Orientation Device That Includes A Latitude Scale, A Latitude Pointer Rotatable About A First Axis Relative To The Latitude Scale, And A Platform Configured To Support An Architectural Model. The Platform Is Mounted On The Latitude Pointer Such That Rotation Of The Pointer About The First Axis Produces A Corresponding Change In The Position Of The Platform Relative To The Latitude Scale. The Apparatus Also Includes A Second Orientation Device That Includes A Time Scale And A Time Pointer Rotatable About A Second Axis Relative To The Time Scale.; The First Orientation Device Is Mounted On The Time Pointer Such That Rotation Of The Time Pointer About The Second Axis Produces A Corresponding Change In The Position Of The Platform Relative To The Time Scale Without Changing The Position Of The Platform Relative To The Latitude Scale. The Apparatus Further Includes A Third Orientation Device That Includes A Day Of The Year Scale, A Gnomon Operatively Oriented Relative To The Day Of The Year Scale, And A Universal Joint Supporting The Third Orientation Device For Movement Relative To A Source Of Light.; The Second Orientation Device Is Mounted On The Third Orientation Device Such That Movement Of The Third Orientation Device On The Universal Joint Produces A Corresponding Change In The Position Of The Platform Relative To The Source Of Light Without Changing The Position Of The Time Pointer Relative To The Time Scale Or The Position Of The Platform Relative To The Latitude Scale.
