Instructions:
Install the Xemu emulator (https://github.lgb.hu/xemu/), drag and drop the code.prg file into it.

Description:
The code displays the shape on the screen by drawing diagonal lines, reversing directions
when edges are reached. For the entire shape to be drawn, some "random" direction changes are
also done.

The code loops forever, drawing the shape over and over.

See commented source code for further implementation details.
