Idea of Start Menu Icon
The icon Start Menu starts with a horizontal rectangle on the bottom with a filled in circle to the left, inside. There is a wide vertical rectangle, with two vertical lines towards the top, sitting on top of the bottom rectangle, on the left side. There is a thinner vertical rectangle right next to the other vertical rectangle with a small line at the bottom.
This Start Menu icon is made in Material Design style
developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 6,100 icons, all in the same style and quality.
