Play with Turtle Art to draw colorful art patterns using a turtle that accepts instructions for movement.

With visual programming blocks, you can snap together programs by compiling (combining) them in ways to create anything you can imagine.

A clock activity
Calculating the hypotenuse and approximating the angle of a right triangle
Stepping through the program is a nice way to visualize the process of approximation
The final result of the approximation.
And on-the-fly function definitions

Tony Forster describes his "adventures" with on-the-fly definitions to create an analog clock in his blog.

Try any of the time or math library functions, e.g.,

localtime().tm_min

sin(x) + sin(pi/2)

Turtle Art can be used to write games, such as a simple falling block game:

Turtle Art supports sensor input:

Students from Caacupé have been sending me examples of their work:
