Look into infinity

In an educational text, accuracy should be important. Foam rubber is
probably hard to find; foam polyurethane (or even foam polyethylene)
is easier to find. Rubber is not polyurethane. (Tin foil is a very
unusual material...)

There are some little programs for modern computer graphical
interfaces that put up a little window to display a magnified version
of the screen at the mouse pointer. When you move the pointer close
to the little screen, you see repeated images. If you can set the
magnification to one, and enlarge the viewing window, you can have
fun! I had maybe 50 or so cascaded borders at once.

Point a closed-circuit TV canera at its own monitor, especially if
the monitor screen image fills about 95% of the frame. You'll want to
hand-hold the TV camera. Lots of fun!

I can't forget the pathetic cluelesss technician who said that if you
pointed a camera at its monitor, you'd destroy the camera. No direct-
view monitor you are likely to see* is bright enough to damage a
camera; and as to internal function, that's just utter and extreme
ignorance. *Rare industrial/military monitors readable in direct
sunlight might be an exception.
