Speaking Clocks
The original HyperCard Speaking Clock and its derivatives can no longer be run with modern computers, unless you have an emulator. I am considering re-engineering but this is time-consuming, and the following represents, currently, where I'm going with this work. I would like to make many more clocks over time.
The new clock, using the same supply text, is called the Epigraphic Clock. It spells the time in a slightly different way and it is still a work in progress. A Processing applet version of this clock is linked below.

I'm working to add audio to the sketch, but this may take some time.

The first working version of the Epigraphic Clock was installed for the Brown University, Student Creative Arts Council Spring Festival, Apr 29-30, 2011, in the Granoff Center for the Creative Arts.
