So I modelled a Decepticon logo in Lightwave tonight, then started playing around with volumetric lighting. I liked the result, so I figured I'd upload it. It's 1024x768, so it's perfect for a wallpaper. Enjoy! http://www.deviantart.com/deviation/31514523/
In case you're curious, here's what the whole model looks like: http://www.antiochforever.com/wrongplot/3d/DLogoModeller.PNG
