The ancient mosaics in the Arles antiquity museum are extensive and exquisite. Also, when I was there I had the pleasure of meeting the superintendant in charge of the maintenance. Here is a picture of her in action, I could just watch her work for hours.
Anyway, she had the little foam pads for everything including the little vacuum cleaner to remove drilled out replaced grout. About halfway through, she turned and dropped a hammer on the priceless mosaic surface from the little bin of tools!!! Definitely an embarassing moment for her, I'm sure. She tried to play it off cool, but I could tell. :)
Update: I recorded my version of the Pulp Fiction trumpet solo since people were asking (I flubbed at least a note or two). I must convert the ginormous .mov file to something compatible to other software so that might take a while.
