This is a screenshot of a loop. We added a variable to how many steps the triangle (look below for triangle script) would take and made it multiply by ten so it would draw a triangle but then add 10 every time drawing it in itself making it keep drawing a triangle bigger and bigger.
When the "t" key is pressed it will activate this script. The script will then put a "pen down" making it draw in black. It will then move 100 steps then turn 60 degrees. It will do this 3 times because of the "repeat (3)" making a triangle.
