Hi Sophie,

more about etoys and math... You know that when you take the car (or
an ellipse, whatever morph) and give it the script

car forward  5
car turn right 2

it will go in a circle.(you ´can put the pen down to see the trace)
Let the kids try that for different speeds and angles - it is always a
circle. WHY?

Make two mice, one moving in a circle, the other one just moving
towards the first (chasing it). Watch the curves that the second mouse
draws.

Cheers

Matthias
