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.

  Currency including coins (using File:Oz-currency.tar.gz)

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)
