Very nice. The CS behind block chains is very cool.

But the "immutable" part dissapear if someone gets 51% of the network with a far superior computing power and rewrites the blocks. There are also other ways of cheating but is not the point

Hey Adrian, I am glad you like it! Yea what you are saying is true, technically speaking you can also remove your blocks locally or re-write them before distributing but doesn't mean it's not immutable. In another words, all documents in your google drive are safe before they are hacked :)
