Today - a screensaver for Mac OS X

by Matt Sephton



Inspired by On Kawara's "Today Series". A series of paintings, each consisting of a monochrome background onto which is inscribed the date of the day on which the individual painting is executed, in the language and according to the calendrical conventions of the country in which Kawara is present when he began it. Kawara created nearly 3,000 date paintings in more than 112 cities worldwide in a project that was planned to end only with his death. He died at age 81 on July 10, 2014.

Source code

Full source code is on GitHub, it really needs modernising to remove legacy and deprecated APIs.
