Just to show those who might suspect i stole this art somewhere, this is how i made it : here's a capture of the various .psd files i did for both the posters and the wallpapers (which can be found in my gallery)
You can see the pattern of the vector shape and the menu in the right showing all the layers and the adjustments.
I hope i convinced you this was definitely not stolen.
More about this incident in an upcoming journal entry.
