A nice celebration of engineering and the everyday heroism of ordinary working men.
And it’s got trucks in it, too.
The night-time one is best.
Take the kids, they will learn something…
Cant work out what on earth its about, unless I’ve missed a bit of the site which explains it? Something about a mechanical puppet.
Certainly fits into the arts bit - cryptic and baffling. 
It’s a giant mechanical ‘puppet’ celebrating the history of mining in Cornwall. First appeared last year and I agree that it was quite impressive with the light show. Worth a look if it visits somewhere near you. I guess, like many engineering exhibits, it will appeal to some but not all.
