This must be one of the most creative proposals ever. I'm afraid the husband-to-be's set the bar rather high for himself in terms of anniversary celebrations!

The most beautiful part of the video has got to be the series of shots showing Sara's expression once she realises that the installation is actually a proposal from her then-boyfriend and now-fiance, George, capturing her reaction as it changes from surprise to pleasant shock once she sees George with the ring.

But enough of my comments already. Go check the proposal out!
