acNeilson
/* acNeilson.java bugly@interserv.com March 1996
*
* Changed name from CrazyCounter.java to acNeilson.java
* Improved readability (because I'm so Alden Bugly) maybe
*
* Note, number is not a parem
*
* Calling syntax that works for me is:
*
*
*
* Passing VALUE (priming the pump) doesn't seem to work.
*
* Renamed Numbers.gif to acNeilson.gif and PSP'd it so the counter
* and my schtick are harmonious.
