Hello all,

I want to create a digram for a paper I am writing which illustrates the
concept of point attractors in a phase plane.  I was going to simply draw
an example but my efforts looked pretty crappy so I figured I'd try
mathematica or some other computer mathematics system out.  So here' s my

Does anyone know of a differential equation whose phase portrait contains
multiple point attractors ?  If the equation had some parameter(s) that
could be set to alter the number and location of these attractors even
better.  I don't care what the equation is, I just want to create a nice
looking picture with 3-5 point attractors and trajectories curving towards

Any tips on how to graph the equations in Mathematica would also be helpful.

If I was a better mathematician I'd know what to do.  As it is I appeal to
your collective wisdom!
