SE-DesktopConstructor
Screenshots: http://se-soft.com/en/Products/DesktopC ... reenshots/ (just linking to them as they're fairly big)... automatically change background image, add desktop clock or calendar, fade desktop with color gradients and more.
Steps: Download portable version.
Status: Portable. Looks like all settings are saved to SE-DesktopConstructor.exe.Options ... Stealth? No: the program modifies the registry in order to change the desktop (HKU\current\Control Panel\Desktop).

SE-ColorMaker
Screenshot:
Steps: Download portable version.... enables you to quickly and accurately find the right color by its characteristics, create and edit color palettes, use different color swatches for all occasions.
Status: Portable and stealth. Similar to DesktopConstructor, saves to SE-ColorMaker.exe.Options
The only way to use this program reasonably is under the "advanced" options where some really nice color picking tools are packed
