On a similar though different theme, I came across these the other day. 20 LEDs on a 2m long copper wire powered by two button cells. All the rage for Xmas table decor in my local pub. Available in a range of colours for less than £2 per piece. Also a range of different lengths starting from 1m with 10 LEDs.
