Alternating Lines Zigzag

So this week's freebie is a little later than I would have liked, but here it is, one of my more favorites, though I do like them all. This one also was inspired by a Dover book. I might wish for more creativity to come up with these all on my own, but everybody needs a starting point, and those Dover people make some of the best stuff ever.

Alternating Lines

Today's freebie is a simple optical illusion design I created from inspiration in a Dover book. It's quite simple, and was easy to create in Illustrator, my creation tool of choice. Check back next week, I will be posting more designs later on.
