If you're looking for some cool July desktop wallpaper of the Mahlerian variety, your search is at an end. Smashing Magazine has just debuted its July lineup of desktop wallpapers, and one of them features Maurice Depestre's of Gustav Mahler's portrait and Vincent van Gogh's "Starry Night" (you can see a preview here).
In case you would like Depestre's Mahler portrait to grace your desktop, there are number of screen size downloads available from Smashing Magazine--it's the 10th calendar down on the July desktop issue. I particularly like the timeline of musical works set against that of Mahler's milestones.
(Quick CPB hint: in case you've never figured out how to change your desktop wallpaper, you can right-click on the image and save it to your computer, then follow this tutorial on how to change the background picture on the desktop. If you're using Firefox, it's even easier - simply right-click on the image, then select "Set as Desktop Background".)
