Description
Imagine you have a robot turtle.??You might think that rather strange, but try to imagine it anyway.??Imagine that this ""turtle"" can move around the floor in response to commands you give it such as:??FORWARD and BACK, which tells the turtle to move forward or backward a certain number of steps, and RIGHT and LEFT which tells the turtle to turn a certain amount right or left.
As the turtle moves, it leaves a trail you can see.??By giving the turtle the right commands, you can have it draw any shape you want.??
Voila!??You have Turtle graphics.??Your Apple II computer screen is the floor and the turtle is a triangle visible on it.
As you experiment with trying to draw shapes using Turtle graphics you may find that thinking in ""Turtle talk"" is much easier for many things than thinking in the ""coordinate talk"" of normal graphics.
Available for both DOS 3.3 and ProDOS and runs on all Apple II computers.
