I have been involved in the making of several props, replicas etc. for the Jorvik Viking Centre in York, the most significant of which was probably the reconstruction of a female skeleton discovered during the diggings at Coppergate. She suffered a life hampered by severe injury, before meeting a grisly fate via the sword of an enemy...

 

 The model was made to be displayed with a Pepper's Ghost  overlay-effect in place, showing how she might have looked in life. The video here explains some of this, and there are further photos below of the skeleton and other artifacts at Jorvik.
