Slight error in Scalar Multiplication paragraph 2. You say Alice calculates
her private point, but I think you mean public (as the scalar is the
private bit right?).

Not much on the "why". Why can't an observer work out the shared time from
seeing 7 o'clock? (maybe show the two public time points instead of just 1)
Why do you need to "bounce" (mirror?) over the x axis?

Though I appreciate the size constraints, and you've managed to fit heaps
in as is.
