Dali Clock is a digital clock. When a digit changes, it "melts" into its new shape. The date is displayed when the mouse is pressed. The window can be made transparent, and foreground and background colors change smoothly.
It is available for X11, MacOS X, iPhone, iPad, Android, Palm WebOS, PalmOS Classic, Monochron and Pebble.
There is no Windows version, so don't ask.

This contains the source code for all versions of Dali Clock.
This is a very old program! The original version was written in 1979 by Steve Capps for the Xerox Alto workstation. In 1984, he ported it to the original Macintosh 128K. (He says that his inspiration was the morphing effect seen in the 1974 short film La Faim by Peter Foldes, one of the first computer-generated key-frame animations.)
In 1991, I (Jamie Zawinski) re-implemented Dali Clock from scratch for X Windows on Unix. It's been fairly popular there ever since.
In 1999, I ported the X11 version to PalmOS. The entertaining thing about this is that the Palm Pilot that I had at the time was an only slightly more powerful machine than the Mac 128K: they had almost the same CPU, and almost the same sized screen! The Palm was about 4x faster, though, and had 16x as much memory. And it weighed a whole lot less.
In 2005, I ported the X11 version to MacOS X, bringing this story full circle.
And more recently, in 2009 I ported it to Palm WebOS; in 2010 I ported it to iOS; and in 2015 Robin Müller-Cajar ported it to Android.
