This is another fledgling attempt to film/edit a painting video, but thought it would be helpful for angieellie and dallyingally, who have asked about my sketchbook (Moleskine) and how well my paint (gouache) plays with the paper.

As for the video itself, I’ve made a note to add some normal speed shots next time, though I did try to slow down the timelapse as it nears the end. Still, it might be hard to tell that the paper handles paint just fine, as long as you don’t scrub or overcorrect large areas. Other sketchbooks are more forgiving, but I like how Moleskines force me not to get too precious or overwork things (much).

Please let me know if you guys have questions or suggestions for videos/subject matter you’d like to see in the future. I definitely want to make more — it’s a lot of fun! Though painting/filming with a tripod between your arms and in your face is kinda tricky.


This past weekend I celebrated the privileges I am fortunate enough to enjoy at a time when so many continue to be denied their basic civil and human rights and dignity (yes that’s a thing that can be taken away Justice Thomas).

I also proved that vegans can still rock the BBQ LIKE. A. BOSS and I celebrated by father-in-law’s penis


“I really love the idea of color and form being one thing. It’s not that I’ve painted on the paper, it’s that the color is the paper. It’s very similar to working with the clay, where the glaze and the clay become one structure—a surface and form.” —Arlene Shechet

Artist Arlene Shechet brings together ceramic- and paper-making practices at Dieu Donné papermaking studio in New York City for a series of cast paper reliefs (some of which are currently on view at the Institute of Contemporary Art in Boston) in a new episode from the ART21 Exclusive series.

candies caught in a sphere

so here’s another variation of the bouncing ball exercise. this time I’ve replace the box constraints:

if (location[i].x<-d+sz || location[i].x>d-sz) velocity[i].x *= -1;
if (location[i].y<-d+sz || location[i].y>d-sz) velocity[i].y *= -1;
if (location[i].z<-d+sz || location[i].z>d-sz) velocity[i].z *= -1;

by sphere constraints:

float distance = dist(0, 0, 0, location[i].x, location[i].y, location[i].z);
if (distance>d-sz) velocity[i].mult(-1);

and it’s of course, again, much more beautiful in Processing than in this animated GIF.


How understanding GPS can help you hit a curveball

Our brains track moving objects by applying one of the algorithms your phone’s GPS uses, according to researchers at the University of Rochester. This same algorithm also explains why we are fooled by several motion-related optical illusions, including the sudden “break” of baseball’s well known “curveball illusion.”

The new open-access study published in PNAS shows that our brains apply an algorithm, known as a Kalman filter, when tracking an object’s position. This algorithm helps the brain process less than perfect visual signals, such as when objects move to the periphery of our visual field where acuity is low.

However, the same algorithm that helps our brain track motion can be tricked by the pattern motion of an object, such as the seams on a spinning baseball, which causes our brain to “see” the ball suddenly drop from its path when, in reality, it curves steadily.

Though we often rely on Global Positioning System (GPS) to get us to our destination, the accuracy of GPS is limited. When the signal is “noisy” or unreliable, your phone’s GPS uses algorithms, including the Kalman filter, to estimate the location of your car based on its past position and speed.

“Like GPS, our visual ability, although quite impressive, has many limitations,” said the study’s coauthor, Duje Tadin, associate professor of brain and cognitive sciences at the University of Rochester.

We see an object’s position with great accuracy when it’s in the center of our visual field. We do poorly, however, at perceiving position when it shifts into our visual periphery; then our estimate of its position becomes unreliable. When that happens, our brain gives greater emphasis to our perception of the object’s motion.

“And, this is where we start seeing fascinating phenomena like the curveball illusion,” said Tadin. “We’ve found that the same algorithm that is used by GPS to track vehicles also explains why we perceive the curveball illusion.”

“A curveball pitch does indeed curve,” said the first author Oh-Sang Kwon, assistant professor at Ulsan National Institute of Science and Technology, South Korea. “But when it is viewed in the visual periphery, the spin of the ball—the motion of the seam pattern—can make it appear to be in a different location than it really is.”

“Here, the brain ‘knows’ that position estimates are unreliable in the periphery, so it relies more on other visual cues, which, in this case, is the motion; the spin of the ball,” said Kwon, who led the study while serving as a research associate in the Center for Visual Science at the University of Rochester.

The perceived motion and position of the curveball depends on where it is in your visual field. So, when the ball enters your periphery, it appears to make an abrupt shift: The infamous and sudden “break” of the curveball as it nears home plate.

The Kalman filter algorithm, named after its coinventor, mathematician Rudolph Kalman, is used to find optimal and integrated solutions from noisy or unreliable data whether in GPS or our brains.

Most of the time our vision does a really good job, but in some cases, such as a breaking curveball, the optimal solution that our brain comes up with belies the actual behavior—and trajectory—of the ball, and the result is an optical illusion.

Therefore, Tadin explained, you have a better chance of hitting a curveball by realizing that our brains, like GPS, can lead us to “see” changes in speed or direction that don’t actually occur when the ball moves from the center of our visual field to the periphery.

These illusions should not be seen as evidence that our brains are poor at perceiving the world around us, though,” explained Tadin. “They are interesting side-effects of neural processes that, in most cases, are extremely efficient at processing ‘noisy’ visual information.“

“This study shows that the solutions that the brain finds for dealing with imperfect information often match optimal solutions that engineers have come up with for similar problems, like your phone’s GPS.”
