English: While MOPAC is over 40 years old, it never had a logo before it was relicensed as an open-source project. The basic design of the logo of a water molecule against a blue background was inspired by a file icon previously used by MOPAC. The molecule and background were rendered in POV-Ray (the background is two infinite planes of blue surrounding a horizon), and the text was added using Inkscape. The open-source highway gothic font signifies MOPAC's historical connection to the Mopac Expressway in Austin, TX.
