The icon is a pie in the classic sense of American pie. It appears that a crust with three slits in the top is with a round pie pan. You cannot see what is inside the pie as the filling is obscured by the crust.
This Pie 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.
