I located the script written by Amy Cook for the Mouse Trail clock but cannot determine how to slow the rotation of the outside day/date text. It works fine as is but for some of us older folks, it rotates too quickly for easy reading. Which line controls the speed and what would you suggest as a slower speed parameter? Many thanks in advance. The code is listed below just as I found it. Although it doesn't credit an author, it seems to match similar code I found elsewhere in the forum that listed Amy's name.

Hi!

Actually that script is not designed for playing with the rotation speed. The speed parameter already given is also responsible for the speed, the stuff is following the mouse.
Just try something like that: find the line saying
speed=0.6;
below that, insert a line like this:
speed2=5;

and at the end of the code alter the last function like this:
setTimeout('Delay()',20*speed2);

Maybe with that you'll get a bit closer to what you want. Play a bit with the value of speed2...
