Trisectors form a subset of mathematical cranks, which in turn are a subset fall cranks.

A very entertaining article about his discussions with trisectors.

In this case "accurate" is an absolute.

It's right or it isn't.

If it isn't then it's a waste of time.

It's fascinating that although you can not trisect an arbitrary angle with compass and straightedge; you CAN trisect an arbitrary angle using origami.
