Check out this TI-83+:

http://flic.kr/s/aHsjLgh3Pz

This is one our school calculators. The entire display has been
reflected horizontally. No idea why -- it just happened spontaneously.
In fact, later in the day, the display was reflected horizontally AND
upside down. Now it is back to just reflected horizontally. (No I did
not photoshop these images.) I might be able to fix it by taking out
all 5 batteries, but I don't really want to.

For several years I have covered my classroom clock and put up a
backwards clock instead. And I have a collection of a dozen watches,
some go forward, some go backward (some with forward displays, some
with reversed displays, one with a mirrored display) -- I wear a
different watch every day. And I have a map of the world in my
classroom that is printed with south on top, north on the bottom.

So I didn't know it until today, but THIS is the calculator I have
always wanted.

Math question: the composition of a horizontal reflection and a
vertical reflection is ... ?

Answer: a 180-degree rotation. So earlier today when it was in
reflected-and-upside-down mode, if you turned the calculator upside
down, the display looked normal.
