The POOL project is illustrating how to use the standard class for
elastically scattering turtles. Here we show how to extend its functionality and combine the collisions
handling with the movements in the field of forces continuously affecting the turtle. Sounds seriously, but
it is nothing more than a not-very-flat surface with a few holes and balls that you should put into these
holes.
Use keyboard arrows to tilt the surface and steer the balls. By the way - the project shows how the keyboard
events are handled.
In this project we also show the use of the render
instruction that allows efficiently create algorithmic patterns over the larger screen areas.
