+  tclock - analog/digital clock for curses.
+  If it gives you joy, then
+  (a) I'm glad
+  (b) you need to get out more :-)

+  (ha.jones@ic.ac.uk). It may be freely distributed as
+  long as this copyright message remains intact, and any
+  modifications are clearly marked as such. [In fact, if
+  you modify it, I wouldn't mind the modifications back,
+  especially if they add any nice features. A good one
+  would be a precalc table for the 60 hand positions, so
+  that the floating point stuff can be ditched. As I said,
+  it was a 20 hackup minute job.]
