Mysteriously deep purple tones with plasma/electric-like explosiveness in deep space, they are actually vignettes from one of my digital fine art images.
Each background is a 1800×1600 pixel JPEG file and weighs less than 300K, conforming to Blogger’s guidelines. These are large and will most likely fill up your whole screen so they are not created for seamless tiling. Also note that they are not shown at full-size here.
Works great with Blogger.com and WordPress.com hosted blogs, Twitter, or for your own personal websites or computer wallpaper.
