In order to help sell my old house, I whipped up a little WP site full of photos of the place. I’m not really sure exactly why, but I made a QR code drawing / painting which linked to the site. The house was sold before I completed this piece, and the code links to a domain that is now pointless to maintain. So, now the link will point to, you guessed it, right here. Until the domain expires. But, the finished piece is still pretty cool to look at. (Part of the lesson learned from this experiment is to link just to a site I plan on maintaining, like this one.)
First I drew the grid on watercolor paper. I painted the ‘black’ squares in a checkerboard pattern of blue and green. Next, I masked off squares about an eighth inch smaller than the grid cells and painted the ‘white’ squares yellow. After this, I still needed more contrast, so I drew alternating diagonal lines on top of the blue and green.
This artwork is also in my scraps collection on DA.
