This special edition Euclid is once again available and well done-- nicely printed, the colours really stand out, and it comes in a 'clamshell' binding:

I submitted this because I've been poking around in my Dover edition of Euclid. Then, yesterday, I found this site. To me it's like what Edward Tufte would do if he published Euclid (Byrne was a 19th-century civil engineer and surveyor from Ireland).

To my delight, I noticed that Taschen has republished this wonderful edition, so I ordered it from Amazon and I'm now awaiting delivery so I can peruse it, enjoy it, and keep it for my children's future math education:
