At least I think this one turned out good.
I've trixed with "The dark side of the moon" LP cover picture.
I also tried this, wich was quit cool:
I've mainly played around with filters.
I'm not that good in Photoshop as some of you.
You might ask what I've changed on the first one.
Well, I've made it darker, and the triangle brighter.
Some lighteffects has been added, and I've also increased the color flow in the outgoing spectrum colors.
