I am in the process of arranging a behind the scenes tour of the
Sagrada Familia.
Lets hope we get one!
If you are interested, there is a very good documentary called Liquid Stone about Mark & Jane Burry and their work at SIAL @ RMIT getting this completed.
Here is a trailer for the documentary, if you can get your hands on it, it is definitely worth a look
