Click Green Flag. Press UP arrow for straight lines. Press UP & LEFT at the same time for the lines to curl left. Press Up & RIGHT at the same time for lines to curl right. Thanks to@haruni459 for the suggestion. It works!!!
Hints: Try to have a quick short burst (Press & release) for the first UP so you have room for the lines to move outward. You can also have the lines move inward. I left the original project @alwayscomputing coding for left & right arrow keys, if you would like to substitute those IF/THEN conditionals in place of mine
