DIY Magnetic Music Laser ShowDIY & Examples Video : http://youtu.be/q8O7w57gncg
This
is a simple way to dump an audio signal into an electro-magnet and make
a music laser show. But this is much better than just spinning or
moving the laser. It creates a "laser microscope" and dumps the magnetic
fields into a small region which is magnified.
Prep Ingredient needed : DIY Magnetic Powder, how to make and store:

is no real "construction" required, per se, asides from pehaps the
electro-magnet if you choose to hand wind it like me. You will require
some items, namely: A laser pointer, A small glass container made of
clear thin glass, a permanent magnet, an electro-magnet, an audio
amplifier, some magnetic power (DIY instructions in link above this
paragraph), and a screen or white wall (you can make an easy screen with
tape and white printer paper)
Setting it up and aligning it can be troublesome. I use a little hot-glue to stick everything in place nice and tight.
Various
things affect the laser show (asides from color and intensity, which
primaily determined by the power and color of the laser)
Placement of the permanent magnet(s) determines the "base"
Placement of the electromagnet determines the "reaction"
Quantity of powder affects "density"
Theoreticals(untested):
Quality of powder should affect reaction
Quality of water/solution should affect reaction, and affect color/intensity
Quality (shape/size/multiple) of electro-magnet affect reaction
