Need a simple accelerometer visualization example!

I’m doing a project using the ADXL335 accelerometer from SparkFun. The actual project I’m using P5 and it’s working great. I’m running workshops in parallel and want to demo the chip in real-time but am currently out of time to build something from scratch. I’m desperate for a simple processing (or something else) sketch that takes my x, y, z values being printed to the serial port from Arduino and visualizes them in some way. Can anyone point me to anything that won’t need a lot of coding time and effort just now?

I find that continuously printing out the normalized (to 1 g) acceleration values along the X, Y and Z axes, while the user orients the accelerometer in different ways, is extremely instructive.

Two digits of accuracy are fine.
