These laser-cut lamps feature designs inspired by the neon signs of Hong Kong. Not only are the lamps cool to look at, but they cast awesome shadows onto your walls and ceiling.

Want to keep neighborhood rugrats off your lawn? Minutephysics and Randall Munroe of xkcd have got you covered, with their step-by-step plan for installing a moat filled with molten hot lava.
