From Wikipedia user page:
Corvi Zeman is yet another geek with too many hobbies. Currently the list includes aviation, restoring an antique printing press, blacksmithing, kayaking, lampwork, glassblowing, scuba diving, japanese calligraphy, hiking, zero-gravity robotics, and music, but it's subject to change without notice. If I contribute an article, it's because I went to look something up for one of these hobbies and it wasn't here yet.
Amusingly, this means I mostly write about things I knew so little about I was attempting to look them up myself. I don't think this ends well, for me or the kitten.
