"Thursday, February 20, 2004 — Should I? More useless site tweaks, bullets and additions/changes all around. Though this isn't why I'm posting, I'm wondering If I should start a 'POTM' (or Picture of the Moment) on the site (usually for EGL/LiteGL, or other funny stuff, anything really), where you can submit (via email) me a pic you want up, with a description. Post on the forums if you give a damn."
It has been suggested that this is the head of one of the co-founders of id Software, either John Romero or John Carmack, depending on the source. John Carmack and John Romero were both instrumental in the development of Quake II. John Romero generally affected long, dark hair and since the head has short sandy-colored hair this suggests that it is John Carmack.
