I wanted to install cath tubes into my mac but I didn't have the cash so I found some clear plastic rods from a old set of window blinds (The thing you twist for then to open and close).

I took a hacksaw and cut slits all over the plastic robs. About a quarter cut will do. Then ever so carefuly I drilled a hole on each side of the rod and inserted a small blue LED in it. I wired it up and walla it works. Not like the real thing but pretty close. The cuts I made into the rods were to mirror the light so it goes though the whole rod. With out the cuts then it wouldn't work.

If more thought was done into this I could of put the plastic ribs into my oven and fourm it into a shape or something.
