It's a logo of a duck. The body of the duck is made up of two "S" shaped lines with the head on top. There is a beak and a dot for an eye. The duck is facing to the right and has a line beneath it to depict the feet.
This Duck 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 15,800 icons, all in the same style and quality.
