TimeGT logo and app icon
TimeGT is a productivity application for Windows, Mac and Linux. It blends the Getting Things Done method with the Eisenhower one but you can certainly use your own.
At the heart of any productivity method there's always the problem of time and managing it effectively. A clock with part of it's cogwheel visible fit that metaphor nicely.
Desktop app & icon
The clock & cog symbol was also used as the app icon for desktops, windows, shortcuts etc. I also did some UI design for the app itself.
