COVER Simulation of a vesicle interacting with a lipid bilayer (lipid head groups in green and blue, tails in cyan; water is not shown). The computation uses a coarse-grained model with over 1 million interaction sites, equivalent to more than 10 million atoms. See the special section beginning on page 783.
