I have had a set of four of my Vectrex images printed at a size of 10" by 15". The set is called Variations on a Right Turn, because each image has virtually the same code behind it. It is five glyphs long, and the only difference is in the right turn command.
I don't have money for frames or space on my wall to hang them up, so I have just stuck them up around the house. On a door. On a desk. On a cd rack. And on the fridge.
A 1 bit threshold was put on the photos before printing them at real scale, 200dpi.
