Flexi-curve memories

When I was learning physics I found my flexi-curve invaluable. Every now and then I did an experiment to prove something or other. Proof of a successful outcome was usually a straight line of readings plotted on a graph. Of course, this hardly ever happened to me. But by bending my flexi-curve carefully through my points and drawing a nice thick line I could give the impression of something mostly straight and that was usually good enough.

I was reminded of my flexi-curve today as I was writing something about bSpline curves which do this kind of line bending for you. I had a look around and it turns out you can still buy flexi-curves. Although this particular product doesn’t have a very good review (but the review is worth reading for a giggle).
