Not knowing exactly what you want to accomplish, I'd start with Foam. You'll need to hit youtube or vimeo for some tutorials. Foam is cool and fun but might be what you want to use.
You can also use Particle World and move the producer around a 3D path. That's another couple of hours of tutorials. Begin by learning how to move the producer around using minimal settings for the physics. Then figure out how to make it emit your 1/0 particles.
\And, of course, there's Particle Playground, a tremendously misunderstood and underused generator. Tons of fun, too, but far more confusing that the others.
Thank you very much, I'll give foam a look and check out you tube for advice on how to set it up.
To clarify, I simply want to visualise data moving across a 2d image, from one building to another, for a small animation and thought a 'cloud' or 'stream' of 0/1 would look cool. Was hoping that I could use a path to direct some particles.
Now I'm off to have a play with foam, thanks again
Text on a path, animate offset and use per character 3D. I don't have time for further explanation but it's quite easy to do.
Text an a path, easy to accomplish and appropriate to the task:

Text animation can be spiced up with tons of interesting effects that bring the glyphs on and take them off. Text animation in AE is as difficult as you wish to make it!
Particles are more fun, though.
You could also just build the little animation in a precomp and move that along the line. I'd pretender the cloud and move the movie.
Thanks again for your help with this.
In the end I used type on a path with range selectors and thrown some particles in for effect (and because they're fun to play with).
