This is the Latest and Greatest version of this PRG.  It all started on a video tape and an A1000 with a DigiView.  
After getting a not so great picture of a lightning storm I wrote my own.  This may not be quite what I set out to do, but here it is.  
There is even a storm mode with sampled sound.  Not my normal Nexus Plots, just a simple math that flows down the y axes.

There are versions of this for the Mac, PX-8, Atari ST, commodore 128 and GEOS.  There is even an Atari 8-bit version, all written by moi.

Make sure you have the latest AMOS libraries installed on your machine and it should run. 

TTFN!
