| 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 [[Activities/TurtleArt/Tutorials/You_be_the_Turtle|You be the turtle]]. It has not been made part of TA yet, but we are working on it. | | == Turtle Art/Tutorials/Turtle Art programming without words == |

| Can you read these examples?

| 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?
| |
| | |
| ==Glossary==
| |
| | |
| This is a listing showing English names for the blocks in the above examples and their icons, either a Unicode character or a graphic. In some cases the same symbol appears on two blocks of different shape, where one is the definition of a subroutine stack or setting of a value in a box, and the other calls the stack or accesses the value.

| One of the Python programmable blocks has a drawing of a python on it. We keep that, and several other blocks that have icons in Walter Bender's original version.
| |
| | |
| ==Palettes==
| |
| | |
| These are the block palettes from a different version of Mokurai's implementation of Iconic Turtle Art. Can you make sense of them?
