It's a very common symbol used to symbolize when you want to shuffle through a few items. It has two arrows which start at both the bottom and top, interwine in the middle and then end at the opposite place (top/bottom). Both arrows point to the right.
This Shuffle 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 16,000 icons, all in the same style and quality.
