The XLerator is a hand dryer found in [usually] upscale bathrooms.  It claims to dry hands in 10-15 seconds and use 80% less energy (than conventional hand-dryers, I'm assuming).  For people that live near me, it's that thing in the new Rockaway movie theaters that feels like a jet engine mounted on the bathroom wall.  I almost don't mind paying $10 to see a movie, provided that I get to play with one of these machines.  I can't not laugh when the air passes through my fingers and makes funny noises.  That will absolutely never get old.
