I've photographed my only Star Wars replica, my scratchbuild of Luke's lightsabre from Part IV. I'm not really a big Star Wars fan (wrong age?) but I've always liked this prop.
The originals were made from old camera flash units that go for a fortune nowadays (because of fans making replicas I suspect!).
Mine is incredibly cheap (and probably a bit inaccurate!), made from an old aluminium pipe, a projector lens and some scraps.
