Galleries
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.
Graphics
color-wheel swirl (jboisture)
David's design (David Morris)
triangulation (Colette)
fireworks (jboisture)
color wheel with shade (jboisture)
color wheel riff (jboisture)
Media

putting images on a map
Maths
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. Pythagoras
And on-the-fly function definitions

Currency including coins (using File:Oz-currency.tar.gz)
graph paper (jelkner)
unit circle (jboisture)
A clock activity
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)
Sensors
Turtle Art supports sensor input:
Using a Hall-effect sensor, you can build a bike odometer in Turtle Art
sound paint Capturing mouse events and using audio to set the pen width
Reading data from multiple sensors (XO hardware only)
love speaks volumes A heart that beats according to sensor input

Games
Turtle Art can be used to write games, such as a simple falling block game:
Space invaders
Presentations
Student work
Students from Caacupé have been sending me examples of their work:

Just for fun
Q: How do I cast keyboard input to a string? A: Use chr().
