We employ molecular dynamics simulations to study the properties of bulk and interfacial water on the atomistic scale. The results of these computer simulations are visualized in the following movies:

1. Relative motion of a chosen pair of water molecules in the continuously rearranging hydrogen-bond network in liquid bulk water:

   High quality (112 MB), low quality (32 MB)

2. Motion of a single water molecule next to a hydrophobic diamond surface:

   High quality (175 MB), low quality (50 MB)

3. Motion of a single water molecule next to a lipid bilayer:

   High quality (397 MB), low quality (110 MB)

A careful stochastic analysis of the fluctuating coordinates shown in the movies reveals the separation- or position-dependent diffusion properties of the molecules and as explained in detail in the corresponding articles.
