Simple music light show (lpt led)

Step 1 What we need

8 colorful pieces of plexi-glass ( or you can use same color, they just need to be discrete, I used 10 x 7 x 0.5 cm )
2 large pieces of transparent plexi-glass ( I used 56 x 12 x 0.3 cm )
8 leds ( I ripped them off from one $3 led torch, basically use wide angle! (with 15 or 45 degree LEDs it is looking bad, use as wide as possible ), high power, white LEDs )
bolts and nuts
black spray
wires
parallel port connector ( I used one from old printer )
hack-saw
sandpapers ( 200 & 400 )

I got the small pieces actually as testing samples from a company making plexi (plexiglass.de), they gave them to me for free. Big thanks for them :-)

Is the parallel port connector male or female? Thanks.

its female on the board, so you will need a male connector

This is my first project so maybe this goes without saying but I was wondering what size wire is used for the connection between the lpt cable and LEDs and how do you terminate at both the port and LED splice points?

How many bolts and nuts? and does size of the bilts and nuts matter?

basicly I used 2 for each square on top to hold it leveled, and the same amount at the bottom to match visual, size is M4. But you can go bigger/ smaller, depends on taste :-)
