The ghosts in Disney's Haunted Mansion are just illusions. But some of them are so surprisingly simple, you can re-create them on your front porch this Halloween.
Just take these singing busts, for example. One clever Instructables user figured out that all he'd need to set up a quartet of haunted singing busts was a projector, karaoke machine and a few beauty-school mannequin heads.
Instructables user TheNewHobbyist went high-tech and decided to integrate an Arduino-powered motion sensing switch (to really frighten the trick-or-treaters). But even if you don't have that kind of programming know-how, you can still follow along with his instructions to create a simplified version with your laptop as the hub.
After changing a few settings on your PC (like installing a black background and hiding any default toolbars, taskbars and app docks), all you need to do is play this YouTube video of the Haunted Mansion's Grim Grinning Ghosts on a loop, then project it onto four carefully placed white busts. Don't forget to amp up the audio with some computer speakers (or TheNewHobbyist's karaoke machine).
