For the last several years we’ve been helping out at the Putnam County Public Library (PCPL) with their Scary Science event on Halloween. It always draws a crowd and love making things for the event.

We usually bring one of our 3D printers to make something there and this year we printed out a mask for an artificial animated eye. And while not original, we made a ghost for a robotic vacuum that was often seen wandering around the library’s lower level cleaning up things.

Topping off our tricks was an updated version of Pepper’s Ghost, an optical illusion that makes animated things appear to be floating, using a tablet and a prism created on our laser cutter. We already have some ideas for next year’s event!
