By all means, update this museum with the most recent available tech.
But keep the old school diorama.
Dioramas are becoming an ancient artifact on their own.
If these things keep many people interested in history ... why the rush to get rid of em' ?
Such displays seem to bring back memories for the old folks and capture the imagination of
some children.
No doubt this is an old and worn out diorama, but I think refurbishment would be easy.
While it might take a while,
it is possible.
I think our resident expert
@rebel brit would be a great help with offering
suggestions.
