The size template I made yesterday for wallpapers was 100 pixels too short, so the original wallpaper had black bands going across the top and bottom, but it was too late to adjust anything by the time I realized it, thus the black border.
370+ layers and about 4 hours total (mostly trying to get the primary shape in the background to clip to itself).
370+ layers?
Anyways, I like it! The way you create transparencies in those marks is great and original!!
