Course Vector Icon

This Course 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 icon has three connected vertical rectangles. The rectangle at the center is slightly than the other two. The first rectangle has a horizontal line towards the top and two towards the bottom, the center one has at towards the top and one at the bottom, and the last has one up top and two at the bottom.
