Turtle Art blocks are named in the current language. Mokurai has created an alternative language-independent "localization" for TA, using symbols rather than words to name the blocks. He hopes that this will make TA accessible to pre-schoolers, after some period working on You be the turtle. It has not been made part of TA yet, but we are working on it.

Can you read these examples?

Tangent to a curve Local maximum with level tangent

Here is a more complicated one.

Numerical integration

This example draws X and Y axes and graphs a function. Then it draws lines from the X axis to the curve, and adds the area of the lines. This approximates a Riemann integral. But never mind that. Can you read the blocks?

Numbers

Some of these functions are named with math symbols +-×÷><=, which are not changed.

Mayan is also a candidate, but it has not yet been added to Unicode.
