I was bored so I made a QR Code for the American Apparel website. I figured it would be a challenge because the design had to be both simple and clean, yet eye catching.
I just got a ton of old books from the late 1800s early 1900s. Most are small pocket sized text books. Pg 83 of New Elementary Algebra; Containing the Rudiments of Science (1872) had this cut out and inserted into it. Any ideas on what the symbol's for? I have no idea.
