For the first seven 'zoid' pictures I started out with a background and a single bright lens flare, then filled in the flare-patterns with lines and patterns, and finally added different glow effects
to all the separate elements. A slow but rewarding effort, and I ended up making only a handfull of these. The originals were in much higher resolution, but I lost most of them in a harddisk crash...
I've learned the lesson of making back-ups of my pictures the hard way!
