At some point in 2000, I found the Persistence of Vision Raytracer,
Pov-Ray. It is basically a programming language for rendering raytraced images. Like vector images, one benefit of these is that, like I did, you can come back years later and render at a higher resolution or from a different angle.
I used it to make a sword logo to match my SMKnight alias and it ended up using it here and there whenever I needed a logo. I used it on websites. I had a grayscale version as an intro graphic in calculator programs I wrote. I used it as a spray logo in Counter Strike. In fact, this even flashes up on the logo on the screen when my projector is starting up.
Much later, putting together a sort of portfolio of work in 2006, I went back and re-rendered it with my full name instead.
