http://invaderjohn.deviantart.com/ You can get the themes from his gallery and easiest way to apply them is by downloading a program called tuneup utilities. It requires that u buy it but there are many ways to get it for free. Hint: TPB and forums. You can also apply icons using the program, and you can search up the icons yourself. Use deviant to search cuz google sucks imo. Programs i use are yahoo weather widget, Miranda IM, CD art display, winamp, & objectdock. Skins for all of them is also available on deviant and some by invaderjohn. Search for Amana on deviant and you should get what your lookin for. Oh and make sure you backup before you apply any Browseui.dll's (used for customizing the browser in windows)cuz you won't boot up if you do it wrong. I suggest some googling for info/instructions before proceeding. Wallpapers: Look for yourself, oh and most of the amana themes are for linux so dont bother if your only running vista.
