Entertaining Vegas news - apparently no one bothered to run the simulation to tell them that if you build a concave building and stick it in a desert, it'll focus sunlight. Go figure. Apparently, guests at one of the casinos have reported getting singed hair and melted plastic bags from lounging out by the pool because the shape of the building focuses sunlight like a magnifying glass.
Remind me not to book a room there. On the other hand, might be fun to go sit out at a safe distance and watch!
