I decided to start a thread to teach all the users her that are new to desktop customization on Windows and OS X and for veterans who want some constructive criticism. Windows Users Basics - Objectbar- A shareware program for making your Windows taskbar look like an OS X one. ObjectBar Skins - http://browse.deviantart.com/customization...r=9&alltime=yes Windowblinds - A shareware program which provides more options that simple visual styles. More buggy IMO, but great for OS X emulation. Windowblinds Skins - http://browse.deviantart.com/customization...r=9&alltime=yes RKLauncher - A dock for Windows. Pretty self-explanatory. Free too. AveDesk/AveTunes - Yahoo! Widget engine alternative. Popular among the customization community, essential in desktop customization of any kind. AveTunes is simply a skinnable iTunes widget for AveDesk.

Have fun spending a million hours trying to get it working Miranda IM Skins - http://browse.deviantart.com/customization...r=9&alltime=yes Styler Toolbar - Essential also, makes your toolbar look ALOT nicer and there are plenty of OS X skins out there. Incredibly easy to use. Loads of other options included besides toolbar skinning. Styler Toolbar skins - http://browse.deviantart.com/customization...r=9&alltime=yes iTunes Multi Plugin - Plugin which makes iTunes 7 skinnable. Only iTunes 7, not 7.1 upwards. Most likely that the developer quit, only bother with it if you don't have a new iPod or Apple TV, iPhone etc. iTunes Multi Plugin skins - http://browse.deviantart.com/customization...r=9&alltime=yes Mac OS X Users Basics - Shapeshifter - A haxie by Unsanity to change the look and feel of Mac OS X Tiger, like Windowblinds for OS X.
