Do you know about Turtle Interpreter?
I create a virtual tortoise.
A virtual tortoise wanders freely.
And the traces are displayed on paper.
This is random. But there is a pleasure to see.
I will make fun with turtles.
The turtle starts in the middle of the paper.
It moves randomly every second up, down, right, left.
Time goes by.
More time has passed.
Time goes by again.
It is the last.
How is it? Is not it amazing?
