Subtle Patterns has a great collection of patterns and textures designers and developers can use in their projects.
To help web designers pick out The Right Pattern, I wrote a Safari Extension that can tile any of the first 200 Subtle Patterns across any website's background. Visit the GitHub project page to download it today!
Upon installing the extension in Safari, a new toolbar item will appear. Clicking it will display a popover containing the available patterns and textures. Clicking one will apply it as a tiled background to the active page's
body element. Enjoy!
