I clicked on the link and saw all the pictures. Sadly the Colosseum still looks like a ruin, and the government of Italy has no money to halt the decay let alone a restoration to former glory.
As a Rome Total War player and an aficionado of all things Roman, I would love to see the Colosseum as it was originally. Yes I realize a restoration would cost billions and modern Italy as a PIIG nation cannot afford it. It really speaks to the immense power, wealth and engineering skill of the ancients that they BUILT this thing so long ago.
I still keep hoping that some internet billionaire will take it upon himself as his life achievement to do a full restoration and that I will get to see it before I die. Barring that, I hope someone will do a very high quality rendering of every inch of the original Colosseum that we can navigate freely in Oculus VR. Maybe even host virtual games with thousands of online participants and spectators.
