Odds are, at some point as kids, we all learned you can focus the rays of the sun through a magnifying glass and burn stuff. Owing to the psychopathy of children, that probably meant roasting ants alive. Hopefully, we've outgrown the laser-death-ray phase—otherwise it's no longer the innocent kind of psychopathy—but the fact remains, it's a cool bit of science.
Turning science into art is Febo, "the engraver that lets you draw and paint with sun."
The Kickstarter-funded project, which raised $81,406 of its $8,000 goal, operates along the same principles guiding those early forays into ant immolation. A magnifying lens is set into a piece of round-shaped wood, then placed on a surface like wood, paper, cork or leather. When the sun's rays are focused and start to burn the surface, move Febo about, leaving behind a charred line its creators call a "cool pencil effect."
For those with no hand-eye coordination or artistic flair, Febo also includes a set of stencils. For those afraid of accidentally sparking a fire—or torching wayward ants—a variety of colored filters are available to slip under the lens when it's not in use.
