Dali Clock 2.24

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 can do funky psychedelic color cycling.

This is a very old program! The original version was written some time in the early 1980s by Steve Capps for the Xerox Alto workstation. In 1984, he ported it to the original Macintosh 128K.

In 1991, I (Jamie Zawinski) re-implemented it from scratch for X Windows on Unix. Its 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.

Finally, in 2005, I ported the X11 version to MacOS X, bringing this story full circle.
