just search a logo or sign you like. Or keep it simple (round, rectangular, ...). You could also @ a blowhole (80 mm fan). It's your case so use your own ideas
Do like this: You decide a logo e.g Flames and then you mirror it so you will have 2 flames, like this: ------------------------------------------ ! T T ! ! h h ! ! e e ! ! T T ! ! O O ! ! P P ! ! ! ! ! ! ! ! ! ------------------------------------------ Sorry for my painting! LOL!
this picture is well old but i still have the same windows in it, completely diff hardware and lighting though, but the windows are the same. now theres an EL string going round the edges of the 3 windows to make the etch light up, the effect is pretty sweet the wave is from a painting by hokusai, appropriately called the great wave dont just do a rectangle window with a generic etching though custom all the way!
heres sketchup drawing of idea i may put a perspex rectanglew on top and add two 120mm fans even mat add some mesh who knows :} http://forums.bit-tech.net/showthread.php?s=&threadid=39838 keep kool -pranks7er-
