I've been playing around with Python Turtle, with the intention of adding finished scripts to trinket.io. A few months ago, I was successful in porting Victor Vasarely's "Plastic Alphabet" in Python and Tk. So, as soon as I learned about trinket.io, I've been trying to port the script into Python and Turtle.
After using brute force to get some boxes drawn in Turtle. This weekend I was able to finish the algorithm to get Turtle to draw columns and rows of boxes. Needless to say, but the power of trinkets is that you can develop Turtle using your preferred Python IDE, and then simply cut and paste the script into a trinket. Enjoy!
