Awesome, that looks like what I want. Thanks for sharing!
I literally just had this printed, following that same blog post. Would recommend Whitewalls, it was a very high quality print. I got the 12x18 size, kind of regret not getting it bigger, but I didn't have the wall space.
If you open the image in a new tab you see that the resolution is good enough to order a print online from one of the countless print services.
