You only need one resister on each LED.

I still think you'd get much better results with ELwire though. LED's won't really work, unless you have a diffuser or some sort.

What are the hots and ground on the keyboard cable? is it red hot (positive) and black ground (negative)?

I believe so.

Been a while since I opened a USB wire.

ha.

I don't think PS2 would have enough current to do what you want.

If it were me, I would find an old USB cord and just strip it down and use that for the power.

After doing some Google'ing, I see that I am apparently wrong. The PS/2 port has 5V, just like USB, at least according to my source.

http://www.epanorama.net/circuits/power_from_pc.html

Also shows a pin-out with the power and ground wires. If you have a multi-meter, and maybe an amp meter, you can check the power specs of the PS/2 port.

LOL they should make little gadgets that are powered off the PS/2 port. never use them for anything else anyways.
