Ulf is the master of 3D-CGI rendered male, gay, erotic hunks with an emphasis on marines and body builders. He has a website and also a yahoo group at gayposerart (You need to log into yahoo groups first)
I love Bullneck's goons! The Greasetank and Yahoo sites are now closed so for his latest ruminations on all thing Goon-ish check out his blog
Quarkmaster is special, not only does he do great 3D art but he creates stories! Check out his gallery at Quarkmaster
Also check out his subsidiary website DamnedToHell (Blasphemy warning!)
I do my CGI art using the Curious Labs software utility called 'Poser 6.0'. These sites are dedicated to male Poser art, gay and otherwise
Paintings, drawings and other non-3D artistic expression
An assortment of web sites which are dedicated to homoerotic images with similar themes to the stories in my galleries. Little or no CGI, just conventional text and pictures
An assortment of interesting blogs
If you want to create your own 3D art then these are the sites you should first visit. There are, quite literally, dozens more, but, in my humble opinion, these are some of the best.
