EDIT - I'm actually selling this costume now as I need space back! details on my blog http://www.deadinsect.co.uk
This is a visually stunning fancy dress costume using LED rope lights and a plastic washing basin to create a deep sea bioluminescent jellyfish thing.
Perfect for Halloween, or any party where it's going to be dark. People will stop in their tracks to start dancing round you, or simply have a spasm. You will feel like a total attention whore, but you will love it too.
