An simulation to answer a puzzle set in NewScientist - it's purely for fun. Edition 3239 page 52. Reproduced without permission Sam has four pet snails. She puts one of them at each corner of a square ABCD with sides 2 meters long. Being very friendly, each snail moves towards its neighbour, snail A to snail B, B to C, and so on, at all times pointing directly towards that neighbour. If a snail moves at a constant speed of 2 meters an hour, how long will it be before they meet?
I couldn't find a snail in the list of sprites,but the beetle does a good enough job.
