Activity: Check with your instructor to see if he/she is interested in awarding extra credit to you for completing the following activity. Research the Internet to find a different optical illusion created with geometric figures. In a word processing document, such as “Word” or “Paint”, recreate the design using the line tool. In Word, turn on the “Drawing” toolbar by going to the menu bar and selecting “View / Toolbars / Drawing”. Send the document to your instructor through VLA email.
