This Load icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,300 icons, all in the same style and quality.
The image is a circle made of circles. The circles vary in size. Starting from the bottom left is the smallest circle that looks like a dot. Going clockwise, the circles get bigger until the biggest one is right next to the dot at the bottom.
