Looking at my avatar, you'll notice the Amiga boingball.
Before Commodore took over Amiga Corp, back in January 1984 the Amiga team wrote a small demo to demonstrate what the Amiga would be capable of, this became known as the Amiga Boingball, an unofficial Amiga logo which demonstrated its ahead of its time capabilities.
For me it represents true innovations, envisioning things with an eye on the future (the Amiga team implemented ideas about a decade ahead of them being implemented on Mac/PC and some of its long lost features are still left to be desired), etc. That's why I drew my personal logo with a Rising Phoenix bringing back innovation in an IMO otherwise pretty stale market.
