Contour plots of the electron-positron spatial density describing the
pair-creation process out of vacuum is animated. At time=0 a supercritical
potential is switched on instantaneously with V(x)=0.5 V0 (1+tanh(x/W))
with V0=2c^2+10^4 and W=0.3/c. The electron and positron are shown here to
grow in production at the center of the potential gradient. The electron
and positron densities are found to maintain their shapes throughout
the initial stage until they are drifted away due to the force generated
by the potential step. Atomic units are adopted in this simulation.
