I've got these on order!

They are already pink, and the fluorescent one looks promising for lighting. Right now I'm experimenting with different methods, so I also have pink LEDs on order. I will also be taking a dremel to one of each of the completed needles to see what effects I can get with grinding them down. Molding will be my last resort, as it's a bit more pricey than a 1-10$ slab of acrylic, but I've seen some really cool looking molded needles, so I may end up trying out Hyokenseisou's idea.
I wouldn't try paint for this application, I'd tend to agree that paint sounds like a bad idea.
