It's a logo of a long diagonal line from the upper left to the bottom right. It covers an image of a person scuba diving with their feet in the upper right and their arms in the bottom left with a scuba tank on their back.
This No Scuba Diving 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.
