To combat vandalism and theft of their holiday displays, many churches and cities are turning to a technological answer. After one of their cows was stolen, St. Marks Episcopal Church in Glen Ellyn, Ill. installed GPS devices in the figurines of its nativity scene. This year the village of Wellington, Fla. added security cameras to protect their display. From the article: "BrickHouse Security in New York City offered churches and synagogues free GPS and cameras to protect their displays this season. Seventy have signed up so far. About 24 of them are also installing security cameras. In Merrick, N.Y., the Chabad Center for Jewish Life is putting GPS in its 8-foot menorah on display in a park."

It probably comes as no surprise, but researchers have found that most of us would gladly put on a mask and fight do-gooders if given super powers. From the article: "But power also acts like strong cologne that affects both the wearer and those within smelling distance, Galinsky noted. The person gains an enhanced sense of their importance, and other people may regard them with greater respect as well as extend leniency toward their actions. That combination makes for an easy slide into corruption."

An anonymous reader writes "Peter Jansen, a PhD student and member of the RepRap community, has constructed a working prototype of an inexpensive table-top laser cutter built out of old CD/DVD drives as an offshoot of his efforts to design an under $200 open-source Selective Laser Sintering (SLS) 3D printer. Where traditional laser cutters use powerful, fixed-focus beams, this new technique dynamically adjusts the focal point of the laser using a reciprocating motion similar to a reciprocating saw, allowing a far less powerful and inexpensive laser diode to be used. The technique is currently limited to cutting black materials to a depth of only a few millimeters, but should still be useful and enabling for Makers and other crafters. The end-goal is to create a hybrid inexpensive 3D printer that can be easily reconfigured for 2D laser cutting, providing powerful making tools to the desktop."
