Transparent Scaffolding for Sightseers

On vacation, I have often come across the main attraction completely obstructed by scaffolding, as necessary maintenance is being done. There has been scaffolding on Big Ben, the Eiffel Tower, Cinderella's Castle, etc. at the time I have been there to view them. I propose that the scaffolding should be built using clear PVC pipes, and any tarps be replaced with clear plastic sheeting. This would allow better viewing of the attraction. Perhaps, for after dark, when the workers are not there, strings of Christmas lights inside the pipes could be lit to add another aspect. I'd suggest neon, but I don't know whether it would work in plastic pipes.
