Should have built-in alternatives to the turtle.

[davidbau]

Currently you can say "wear red" (or any color) to change the turtle shell, or "wear url" to wear an arbitrary image.

We should also support (and document) a few other built-in characters such as "hero"/"heroine", "mouse", "cat", "dog", "rocket", "car", "boat", "fish"; and maybe a few built-in abstract shapes such as "circle", "square", "triangle", "arrow".

A palette of built-in characters would be a more classroom-friendly alternative to Scratch's drawing program (which is where kids will spend all their time instead of programming), or going to the internet to look for image urls (which is another way for kids to spend all their time instead of learning to program).

If we allow color combinations with a dozen built-in shapes, that's plenty of room for personalization for kids in a classroom setting.

This sounds great. Is this already implemented in the code so that I could define alternative shapes ?

If not please point me to the needed changes in the code.
