I first saw these on the WL site, but they have since vanished (perhaps the owner realized what a scumbad steve is?) They have a very intriguing effect, and it appears that the whole 'blade' is avalibe for ~$25 in their parts section... should be easy to fabricate a handle or modify a cheep "Lightsaber" handle... Thoughts?
