Idea of Automatic Icon
The Automatic icon, a square with edges curved instead of pointed, with a gear inside. The gear takes up most of the profile of the square, and seems to be the smaller cog that fits next to a larger one, based on the spacing of the teeth.
This Automatic 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 6,200 icons, all in the same style and quality.
