Crocell

Saw his sigil posted in an unrelated thread so I figured I should check him out. Described as a djinn who teaches geometry. 

Now for the "coincidence", I just started learning C# and picking up web design again. I found the courses to be filled with djinn possessed people, including the teachers. This made sense to me since I asked for good teachers and co-students in advance, and djinn think in binary so it makes sense they'd be good at this. But I didn't consider they may be behind the languages themselves. I have reason to believe they at least inspired the creation of C in different incarnations.

Good one, he's shown wearing "programmer socks".
