have a definition move on its own?

Hi I am relatively new to Grasshopper and am still learning how to use it. I have finally composed a definition to do what I want it to do using point attractors.

Now I am trying to figure out a way to get the points to move (along a line) on their own at simultaneous times to see the different effects that could result from 3 moving points at once.  I tried to follow the discussion boards to find similar definitions on animation, but I'm still unclear on how I can apply that to my definition.  Can anyone help?  I would really appreciate it.  The original rhino and grasshopper files are attached.
