Mine actually was given to me by my high-school gym teacher. In volleyball I was always going up at the net to block spikes, and my teacher started calling me 'skywalker', as a friendly joke. (He wasn't teasing... I think he liked the effort...) Anyway, I took it on as my handle when I was first on-line gaming, years ago. Strangely, in the last few years it's become even more appropriate, as I rediscovered my love of the Star Wars movies, and started buying the toys for my kids.
