Confusion Vector Icon

This Confusion 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 15,000 icons, all in the same style and quality.
The image is a person's bald head. The person is facing the right and doesn't have a mouth or eyes. The person also doesn't have ears but there is a question mark on the person's head where the ear would be.
