In tenth-grade chemistry, I converted my name to an unpronounceable symbol, like Prince was doing at the time.
As I recall it was a bunch of math gibberish, like a compound expression inside a cube root, and Kilroy was peeking over the top of it, and the whole thing had an integral or something too. Mrs. Stockwell was tolerant enough to let me use the symbol on all my classwork, even going so far as to ask me which ASCII symbol she should use for me in the computer where she kept the grades.
The Student Formerly Known as David Malki (these antics preceded, and I suppose foreshadowed, the exclamation point) is no longer, but my fascination with preposterous semiotics continues. Thus my new shirt. Enjoy!
