That gold-wire-and-circle-of-nails art thing [String Art!]

Postby Jorpho » Sun Jan 17, 2010 7:46 pm UTC

A great many years ago, when at math summer camp, we did this one activity that involved a circle with one hundred evenly-spaced points around its circumference. The idea was that you could draw straight lines between certain sequences of points and end up with different designs, depending on how you generated the sequence. Many of the designs were curved shapes with differing numbers of lobes.

It came to mind recently when I happened to see a piece of folk art designed around the same principle, involving a circle of nails with wire criscrossing the circle instead of just pencil lines between the points. I'd like to try making something like that... only I've completely forgotten the details, and I certainly can't remember what you'd call the darn thing.

Can anyone here help me out?

Like this?

I've always called it string art.

If it's that thing justaman linked, I've only ever heard them called "mystic rose."

Not only have I seen it done in the fashion justaman linked, but I've seen right angles done the same way, with certain points on the X and Y axes, and if you drew a line or ran a piece of string from one point on the X axis to another point on the Y axis, and so on and so forth, you'd get various forms of string art.

I think it can be done on any geometric shape, really. I remember doing them in the arts and crafts room at the Boys and Girls Club one day during the summer.

Ahh, yes, splendid! Thank you.

I'm kind of surprised I don't see this sort of thing more often, actually. I think it looks real pretty, aside from being an excellent way to kill time. Is it not so?

I made one of those for my mother when I was a teenager, and since then I've written a few programs to draw these designs, using circles, ellipses or general Lissajous figures as the base shape.

Google "Caustic Curve". For the "rectangular" one, do a search for "Astroid". Maybe start a thread in the "Mathematics" or "Coding" forums.
