Ironman

but a person can run through a wall -

 

A 3m x 2m sheet of iron, 6mm thick, the form cut out with the oxy-acetylene torch, one half bent forward and the other bent back and welded on to the base plate. Iron is fascinating - and I have been lucky enough to get to know an ornamental iron worker who helped me. thanks Andy - for your patient explanation and also for the other projects we did.

I can imagine many more iron sculptures, but there are always transport and space problems (perhaps that will be solved one day) apropos transport problems: thanks to all those who turned him round and all who transported him (380kg) and to all the ancient civilisations that discovered putting round rollers underneath - the good old work = power x distance principle.
