The folks at Mandolux.com have released several new series in their Mac desktop images backgrounds portfolio. The Web site has released 40 imaged from the Tetra series, a series taken largely from playing with negatives and other imagery, 40 images in a series called Canneries, taken from closeups of aluminum cans, and a brand new series called 4.95. 4.95 is a series of garishly colored images, for those who can take such a thing.
These desktop images join literally hundreds of other desktop images for your Mac, as well as icons and other resources.
