Tacky Turtle

Tacky turtle is a virtual machine that runs randomly generated programs (any combinations of symbols is a valid program), and the program controls a turtle which leaves a trail behind it.

The program's memory is a 'tape' which you can see on the right of the screen.

Click 'Play' and then 'Randomize'.
