Timer in C# - Visual Studio

Hi,

I'm working on a C# script the will repulse points on a surface or mesh. What I need is the following

1. Create a number of points in random positions on surface (I can do this)

2. Assign a repulsion force between points within a certain radius (I can do this).

3. Use the timer to accelerate a point depending on direction and magnitude of force.

2. Assign a repulsion force betw................

3.

2.

3.

So my problem is that I want this to work as an itterative process, where I in the end slowly will damp the system and have the points nicely spread out on the surface.

In Grasshopper I want to be able to connect a timer to the object and just let it run.

How can I do this?
