This Wolfram Alpha 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 4,400 icons, all in the same style and quality.
We've received the idea on April 16, 2012 and created the icons on May 20, 2012
Popular Software Icons: VLC, Wolfram Alpha, etc
Popular software doesn't get much icon support, but it needs it to be part of the unified consistent look, pick popular specific software with simplistic but unique vector styles for the icons
