Visualizations of vibration patterns from 1787 by Ernst Chladni:
One of Chladni’s best-known achievements was inventing a technique to show the various modes of vibration of a rigid surface. First published in 1787 in his book Entdeckungen über die Theorie des Klanges, the technique consists of drawing a bow over a (circular, square, or rectangular) plate or membrane whose surface is lightly covered with sand. When stroked, a given plate will resonate at one of its natural frequencies. The sand bounces about on the plate until settling at nodal points (areas of zero movement) thereby producing intricate patterns. These patterns are now called Chladni figures.

"while sitting on brighton beach (UK) back in 2005 with my new girlfriend, verity, i thought the view of our feet pointing out to sea would make a nice photo. ever since then we’ve continued to document our travels in this way, resulting in a collection of over 100 photos. in 2011 the series took a new twist with the arrival of a third set of feet – our daughter matilda. you can already see her little feet getting bigger and bigger." - text and photos by tom robinson

By Aganetha Dyck, in a most unusual collaboration, this artist begins the process with broken and damaged figurines which strategically have wax or honey placed on them to attract the bees. It then becomes the bees job to repair the figurines by building their meticulous honeycomb over the contours and indents.
Keokuk is in the process of tearing this building down. The last couple days have began with the sound of bad classic-rock music, hammers, and burly men dealing with hangovers. It always makes me sad to see a house come down in this town, no matter how necessary it may be. I instantly think about generations of different families living inside them, wondering when exactly it went to shit.
You can’t see it in this photo, but this house is nearly half a block long. At some point, somebody built a business onto the back, and a garage just behind that. The woodwork that decorates the porch, though warped, is hand-cut and intricate. Certainly, at some point in time, this house was somebody’s pride and joy. In its entire lifespan, it was probably multiple people’s pride and joy. If that’s not sad, then I don’t know what is.
Today, the final moments of attention this house will ever receive, is devoted to little more than fart jokes and pulling rusty nails. I suddenly want to know about the history of this house. I want to know when it went to shit.
I suppose that’s what happens to most things, though, with enough time.
