These are the Weeping Angel string lights available from ThinkGeek. A string of ten costs $25 and the angels, which alternate between eyes covered and attacking, can be set to blink on and off. I just bought two strings to accentuate my Doctor Who Christmas tree Halloween costume this year. I am going to win the costume contest. Or I am going to choke whoever wins the costume contest with a string of Weeping Angel lights. God willing, I'll still go home with a girl dressed like a character from Bob's Burgers.
Keep going for one more shot.
Thanks to Stephanie A, who's already taped her eyelids open and hydrates them every so often with one of those spray-bottle/fan combos.
