This isn't exactly a replica, just put it together after reading this in the 
early morning hours here.

That was an interesting story about this juggler, I hadn't seen it before... 
or don't remember it from so many years ago. I used to stare at the stuff on 
the Amiga displays in store windows, too.  ;^)

Here's the rather simplistic (yet long) SDL you can try to work with if you 
want. Also uses the oscillating clock from clockmod.inc by Chris Colefax, 
done so I could move the arms. No doubt this could be improved upon so I 
leave that up to you! (Wow! it's a longer file than I thought! sorry). 
Especially badly done, perhaps, is the ultra simple (and separate) splines 
for ball motions. First thing that came to mind I tried.
