The curved design of the Vdara Hotel in Las Vegas, designed by Rafael Violy, basically turned the building into a giant magnifying glass, intensifying light so much that it harmed hotel guests and earned it the nickname "Death Ray Hotel.". /BaseFont /Helvetica An excavation extending across an entire site was progressing toward a total depth of 14 m below grade.
