Figure 2-10. Hinging flips over a VGT
c. Select Sequence and Prepare Flips. With the flips properly hinged in place on the frame of
the base VGT, you may present the amplifying information contained on the flips in the desired
sequence. Your base foil contains the basic information. You decide what elements belong on the base
foil, and what goes on each flip.
(1) You prepare the base foil and mount it in its frame. You then prepare the flips and
hinge them in the desired pattern. Using the base foil and the flips, you can present a series of ideas or
instructional points with this multiple-celled VGT. Figure 2-11 illustrates the concept of multi-cell VGT
presentation. Note the registration marks on each cell.
(2) You must know if the receiver of your VGTs uses a front or rear projection method.
You must know this in order to determine how to mount your films. For front screen projection, you
mount the foils right side up; for rear screen projection, you mount them face down on the rear.
