I have this idea of cosplaying the 2009 movie version of Astro Boy and want to create the glowing "blue core" effect like this; ... m-5862.jpg ... m-5876.jpg
Naturally, I want to use LEDs but looking for advice on how to go by it.
My immediate thought is to use something like this; ... 1SA5C9H6JQ
wrap blue cellophane around it and attach it under my shirt but I thought I'd ask people with more experience in LED effects for cosplay. What do you all suggest?
