Often, when it comes to DIY projects, we create our own circles by starting from a center point. Whether a compass, string guide, or specialized cutting jig, a circle emerges from our pencils or saws precisely because we've created an established and consistent distance from a single origin.
But, what happens when the shape already exists, and you need to know how to find the center of a circle? You can do it in less than a minute without any specialized math, memorizing a formula, or even knowing what pi is.
I'm a big fan of geometric shapes in DIY projects, but when it comes to woodworking, it can be difficult to anticipate all the math when working with angles other than 90-degrees.
Swiss artist Felice Varini has been experimenting with optical illustions for nearly thirty years, and from the impressive scale and experience of these anamorphic installations, I think it's say to say he's figured it out.
"Step-by-step" is a dedicated tool for helping children learn the basics of geometry through animation. It resembles an iPad with a lamp mounted to a beautiful wooden enclosure that allows kids to operate the tool on their own and film and view their own animated movies.
I know, it's kinda hard to explain. So, watch this video. It's pretty amazing:
How does one achieve such an Easter egg? Fancy laser cutters? Computer controlled carving machines? Ancient, secret Easten European techniques that are only known by, like, six living people?
Nope, just a pattern and some patience. Which means you can do it too.
Yeah, buddy...Check out this super cool "himmeli" mobile my friend Elizabeth Abernathy [the brains behind Nuno mag] created using an upcycled, out-of-date phone book. (Right, it's out of date cause its a phone book. Got it.)
Elizabeth notes that hillemi are "
