This is something I through together once when I had to do something similar. (Actually at the time it was a one liner, but I'm really bored at the moment, so I played around)

Code:
(01:40:26+deco@DeCoBuntu)
[~]$cat track
#!/bin/bash
if [[ -z $1 ]];then
echo "Usage: `basename $0` <process to watch> <delay between checks>"
echo "If Delay not specified, default is 5 seconds"
exit
fi

usage=`top -b1 -n1|grep -i $1|awk '{print $10}'`
while true
do 
echo -ne "$1 is using $usage percent of the total memory"
echo -ne "\r"
if [[ -n $2 ]];then
sleep $2
else
sleep 5
fi
usage=`top -b1 -n1|grep -i $1|awk '{print $10}'`
done
(01:42:10+deco@DeCoBuntu)
[~]$./track
Usage: track <process to watch> <delay between checks>
If Delay not specified, default is 5 seconds
(01:45:45+deco@DeCoBuntu)
[~]$./track firefox 2
firefox is using 16.5 percent of the total memory

I'm pretty certain the switches on top could be done better, but honestly, I'm not very good at this kind of thing.

deco(6x)							XScreenSaver manual							  deco(6x)

NAME

       deco - draw tacky 70s basement wall panelling

SYNOPSIS

       deco  [-display	host:display.screen] [-foreground color] [-background color] [-window] [-root] [-mono] [-install] [-visual visual] [-delay
       seconds] [-max-depth int] [-min-width int] [-min-height int] [-line-width yIint] [-smooth-colors] [-golden-ratio] [-mondrian] [-fps]

DESCRIPTION

       The deco program subdivides and colors rectangles randomly.  It looks kind of like Brady-Bunch-era rec-room wall  paneling.   (Raven  says:
       "This screensaver is ugly enough to peel paint.")  Can also produce more aesthetically pleasing displays via options.

OPTIONS

       deco accepts the following options:

       -window Draw on a newly-created window.	This is the default.

       -root   Draw on the root window.

       -mono   If on a color display, pretend we're on a monochrome display.

       -install
	       Install a private colormap for the window.

       -visual visual
	       Specify which visual to use.  Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.

       -delay seconds
	       How long to wait before starting over.  Default 5 seconds.

       -max-depth integer
	       How deep to subdivide.  Default 12.

       -min-width integer

       -min-height integer
	       The size of the smallest rectangle to draw.  Default 20x20.

       -line-width integer
	       Width of lines drawn between rectangles. Default zero (minimal width).

       -smooth-colors

       -no-smooth-colors
	       Whether to use a smooth color palette instead of a random one.  Less jarring. Default False.

       -golden-ratio

       -no-golden-ratio
	       Whether	to  subdivide rectangles using the golden ratio instead of 1/2.  This ratio is supposed to be more aesthetically pleasing.
	       Default false.

       -mondrian

       -no-mondrian
	       Whether to imitiate style of some famous paintings by Piet Mondrian.  Overrides line-width and colormap options. Default false.

       -fps    Display the current frame rate and CPU load.

ENVIRONMENT

       DISPLAY to get the default host and display number.

       XENVIRONMENT
	       to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
