Ok, it is not glowing spaghetti it is in fact made out of optical fiber (surprise! 
). One really cool with the Laluna fiber optic lamp is that you can change the color of the lighting by using a turning color wheel:
The lamp is available in two sizes and the price is between $1000 to $1200.

I don’t like the colored ones, but the white version is so so pretty. Too bad it’s also extremely expensive.
