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.
