We measure the source point coordinates p1 = (0, 0), p2 = (2.1, 0), and p3 = (-.1, 2.3).

For the target points on the upper (left) mirror we measure q1 = (.5,8.3), q2 = (.9,7.3), and q3 = (-.3,8.1) From this data the affine transformation calculator finds r s theta phi e f -.51 .35 112 106 .5 8.3 For the target points on the upper right image we measure q1 = (5.5,6.4), q2 = (5.1,5.7), and q3 = (6.3,5.8) From this data the affine transformation calculator finds r s theta phi e f .38 .44 -120 -129 5.5 6.4 For the target points on the monitor we measure q1 = (.7,-1.7), q2 = (1,-.5), and q3 = (-.4,-1.1) From this data the affine transformation calculator finds r s theta phi e f .59 .55 76 59 .7 1.7 For the target points on the right mirror we measure q1 = (6.2,-1.5), q2 = (5.5,-.5), and q3 = (6.9,-.9) From this data the affine transformation calculator finds r s theta phi e f -.58 .40 -60 -46 6.2 -1.5

Combining these we have these IFS rules and this picture. Here is the videofeedback image for comparison.
