Some notes on each video, in order:

1. This shows the static model (in which dendritic cells don't move) with a reduced number of dendritic cells, and rotation to give the viewer a better sense of the 3D nature of the model.
2. This shows the static model with a more typical number of dendritic cells.
3. This shows the linear model (in which dendritic cells move linearly from the outer edge of the node to a random location), with a reduced number of dendritic cells.
4. This shows the random model (in which dendritic cells have random movement akin to T-cells, albeit more restricted) with a reduced number of dendritic cells.

The commands to produce these were,

1. StatLN -z -D 100
2. StatLN -z
3. LinearLN -z -D 100
4. RandomLN -z -D 100

Where "-z" engages the graphical output. This particular output requires GLSC3D, however.
