The location of the next step is “current location + random Gaussian numbers”, i.e.,

*x[k + 1] = x[k] + rnorm(1)*

*y[k + 1] = y[k] + rnorm(1)*

where *(x, y)* stands for the location of a point.

None (invisible `NULL`

).

The maximum number of steps in the motion is specified in
`ani.options('nmax')`

.
