Nasty or not, it’s a nice pattern that tiles. Like they all do.

Similar to original, but without gaps in between the arrows. This seamless pattern was created from a rectangular tile. To get the tile, select the rectangle in Inkscape and use shift+alt+i.

The first pattern on here using opacity. Try it on a site with a colored background, or even using mixed colors.

This seamless background image should look nice on websites. It has a dark blue gray texture with vertical stripes, it tiles seamlessly and, like all of the background images here, it's free. So, if you like it, take it!

Not strictly seamless in that opposite edges are not identical. But they do marry up to make an interesting pattern

Submitted by DomainsInfo – wtf, right? But hey, a free pattern.

Wasn't satisfied with the original's colouring. Too much component transfer and colormatrixes yet the results are lacking a bit. So this time it is a simple black to transparent fade, making it possible remixing easily once there will be other blending modes supported as well. Probably in inkscape 0.92.
