Part of a school project I did, and I thought it looked cool enough for a wallpaper, so I hope everyone enjoys. They are in SVG, and I have a few PNGs of them at 1680x1050. Let me know if they are wanted.
They were originally created in Adobe Illustrator CS4. My school assignments needed to be in .ai format, so yeah. I know, I know, not gpl... whatever. They work just fine in inkscape.
