Different resolution wallpapers go from 1024x768 to 1920x1200, 8 different resolutions in the bundle. The last primes on the right are the twins 20639 & 20641. I've included enough families of circles to go a little over 21000, so these images contain all correct prime numbers in their range.
I've created a 24"x36" print of the map of factors at the origin that looks very cool. I have limited prints, so don't miss the chance to own the first one of a kind poster I created. Contact me directly to my e-mail, or look for the poster on ebay:
I'm selling these for $20 including shipping within USA and Canada.
The following is the image I used in lesser resolution. The actual file is about 60MB with a resolution of 10800x7000 pixels.
