After I had completed the black and white Sharpie drawings for the Numerically Controlled Poster Series with artist Matt W. Moore, released over the summer [see MWM graphics/aarn: numerically controlled drawing series [misc]], I decided to do some experiments with some colors. I had one fresh red Sharpie and one blue on hand. I did one pass with a red marker at 100%, and then a second pass where I scaled down the blue layer to 98% and centered the transformation around the center vertex in the artwork.
When Matt came to pick up the other drawings, I gave him TWO of these 3d drawings. He released them on Black Friday, and they are for sale in his online store along with the remaining black and white drawings from the original release. Scoop them up.
