This little program written in C/C++ with assemby does a neat
tube type effect.  It's the second file that I've decided to 
release.  If you have any comments or suggestion, you can

Oh you may use the + and - to speed things up or slow them down.
It's not fully optimized, ie calculating 5129 points each loop
even if they need not be. I haven't decided to release the source 
yet.  To most this effect should be self explanitory, but I know
there are people trying to learn just like I am.
