If you need donut shaped icons, then you came to the right place.
I could not find a "loops" set so I have decided to create my own one by using "RealWorld Icon Editor 2010.1". There are 5 icon roles for each icon type. All icons have the .ico file type. Those icons are fully compatible for Windows Vista and Windows 7. Those cool icons can be used when creating .theme files for Windows Vista and .themepack files for Windows 7 when creating themes. There are a total of 31 icons (30 colored icons and 1 transparent icon).
Please note that the file size is relatively large (24.9MB) so please be patient when downloading those icons. You are welcome to use my icons for all your project creativity needs.
