Hallowe'en is my favorite holiday: I like seeing costumes (and walking around in my own), and seeing what people do to decorate their houses, yards, etc. For the second year in a row though, I've failed to come up with a really good scheme for making my own place appropriately spooky. So, in hopes of loosing some inspiration for myself and others, I ask today what you're doing to spookify your surroundings (or your person) tomorrow, especially if it means using technology in interesting ways. Sensor-activated scary sounds or lights? An Arduino or Raspberry Pi-controlled costume? Elaborate trap-door? Infrasonic hackle-raising subwoofer install? Maybe one year Alek Komarnitsky will switch to Hallowe'en instead of Christmas, and offer a webcam-equipped remote-controllable haunt.
