Turtle Art is an activity with a Logo-inspired graphical "turtle" that draws colorful art based on Scratch-like snap-together visual programming elements.
Although it has a turtle, supports neither procedures nor recursion, so it should not be seen as a Logo replacement.
There are five palettes of program elements available for program construction. Conditions for the If block are a different shape than numeric parameters used by the other blocks.
