loads of people have done one of these but I thought I'd give it a shot, took a staggering 5 minutes and about the same time to render. this is a lower res version higher one here http://disorderx.deviantart.com/art/Electro-Ball-68426909
looks really nice, what program did you use? if you dont mind me asking. Also GIMP 2.4xx was released a few days ago, and it blows photoshop away
Oops, I just noticed the one at deviantart is actually smaller, I can do any screen res by request if anyone wants (1600x etc) this one is the working one I use a prog called Bryce its mainly for landscapes and waterscapes but allows you to mess around with shapes and do some simple modeling, not as complex as some of the other more powerful tools like Blender but its excellent at getting decent results quickly and with not to much effort. As for the 2D/ post processing side I use paint shop pro.
