Sometimes I search my blog for this picture and scratch my head in puzzlement that it’s not here, before remembering that I posted it on Google Plus back when I used that.
So here it is. Stephen Guerin (the shaven one) displays his canvas print of one of my designs.
The colors came out better than I hoped, in stark contrast to a couple of mugs with related designs that I got from the same shop.
I may as well say how this works. For each pixel, convert the coordinates to Gray code, then
thus assigning each bit of the coordinates to some bit of the color channels; then convert back from Gray code to get the final colors.
One of those two mugs has since grown on me some.
