I think that the resolution of the empeg's display is not high enough to reproduce that effect. Or, rather, if it did, it would obscure most of the visualization.

Remember that the empeg's display is only 128x32, and even the small font takes up, what, six vertical pixels? So adding at least two pixels for a border, possibly more, means that the small font would take up a quarter of the screen. Maybe that's not so bad.
