Like the name suggests, this background image consists of a pattern of dark bricks. It may be an option for you, if you are looking for something that looks like a brick wall for use as a background on web pages. It's not a masterpiece, but looks pretty nice when is tiled.

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.

This one is so simple, yet so good. And you know it. Has to be in the collection.

Not so subtle. These tileable wood patterns are very useful.

A repeating background with seamless texture of stone. There haven't been any stone-like backgrounds for a while, so I have decided to create one more. The rest can be found in the appropriate category.

Vertical lines with a bumpy, yet crisp, feel to it.

This one resembles a black concrete wall when is tiled. It should look great, at least with dark website themes.

I’m guessing this is related to the Sony Vaio? It’s a nice pattern no matter where it’s from.
