This one is a personal favourite of mine. I initially made the head and fitted the retro headphones to it. Afterwards a friend suggested fitting lights to the headphones. 
I replaced all the cabling with 240v rated cable and after removing the internals I fitted lights to the headphone cups.
The result looks amazing in any room.
 
I am not sure if I will make another but if I do no two are the same.
