This is the Icon for Angry. It is a circle shaped face, with teeth showing in a half circle grimace. The eyes are ovals that are slanted downwards, with two lines above the eyes slanted downwards also that make up the eyebrows.
This Angry 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.
