It is an invisibility cloak! Well... almost. The idea is there and it is getting closer to being what people want it to be, but right now it is in stages of infancy. Look at the picture to see what I mean.
What we have here is what I might call a "Chameleon cloak". It still shows off your figure, but it makes you look transparent, to a certain degree. As best seen in the above picture.
With that being said; I still want one!
