grid seems like the right choice to me (it comes bundled with R, so
it's not available as a separate package). Here's an example that may
give you a few hints:

library(grid)
grid.newpage()
for (i in 1:30)
    grid.lines(x = 0:20/21, y = sin(70 * runif(1) * 0:20/21),
               vp = viewport(x = runif(1), y = runif(1), height =
0.05, width = 0.05))

See the package documentation, or Paul Murrell's book "R Graphics" for more.
