Here is my take:
Update: More "bling bling", more compilation time... (and trying @Stefan's brilliant idea)
Update 2 Thanks to Stefan, I have seen that the previous version was only working in the QtikZ environment but nowhere(I guess) else. For some reason beyond me, the fadings are still not displayed correctly in Adobe Reader but at least it works (almost) properly in SumatraPDF on Windows. Sorry for the inconvenience and Happy New Year everyone!

If you compile this several times, you'll see that the first three GUIDs change, whereas the last three don't, because they're defined with a fixed seed.
