Chameleon for Windows 8 is a simple desktop customization application that will allow you to pick or automatically change your lock screen background.
Windows 8 offers tons of user customization but the included backgrounds can become boring very quickly. Chameleon for Windows 8 keeps your lock screen background interesting by cycling through new photos at a set interval. You can set it to change anywhere between 15 minutes and two days. Chameleon for Windows 8 provides a great way to be greeted with a different, interesting photo every time you log in.
Beyond setting lock screen backgrounds, Chameleon for Windows 8 doesn't really do much else. There's no way to change the background image for the Windows 8 start menu. You'll be stuck with the default themes that Microsoft included.
While the quality of the photography in Chameleon for Windows 8 is great, the resolution left much to be desired. Photos loaded quickly but that's because they were compressed. Pictures look fuzzy and weren't displayed at the native resolution of our monitors. We wish that Chameleon for Windows 8 had a way to automatically download backgrounds at the native resolution of the screen.
Overall, Chameleon for Windows 8 provides a fun way to get fresh, interesting backgrounds for your lock screen but leaves much to be desired for the quality of the photographs.
