Kisses, Kisses by Yael Kanarek

http://www.yaelkanarek.com/netart/kisses-kisses-2016

Both of the pieces are a form of digital paintings or visual generations. What I admire about them is the interactive input in creating a cohesive piece. I am not aware of the algorithms used or the input audience members were allowed to share in forming the interaction, but a subject I think was overlooked was the physicality of these pieces and their linkage to audience members. I think if the interaction was an important part, the documentation of the interaction is also pivotal in display, otherwise it seems like another painting.

Running Drawings

For my final project, I would like to create some data visualizations of the running routes I do in Pittsburgh. These visualizations would be algorithmic drawings documented as a running diary of my daily or weekly runs. What I normally do not notice on a run are the larger gestures I make and the shapes, speed rates, and heart rate variations accompanying the larger gesture of a route. Mapping out these routes, and creating algorithmic drawings from the resulting shapes would not only visualize the “gestures” I am constantly making but unaware of, but also document trends on the routes which can affect my running and the way we look at a route retrospectively.  I would be using turtle functions to follow the path, and arrays and for loops to create algorithmic patterns/visuals for a more appealing visualization of how I felt that day.

My process for this project started with playing around with the abstraction and composition of different polygons and their color. The mouse interaction and randomization were added after.

Surround Sounds by Christian Marclay

Surround Sounds is an art installation by Christian Marclay which entraps viewers in a room with projections that play “music” through their animation of visual onomatopoeias. The room is actually silent, but by using the animations to take over the space, sound can be envisioned, or felt in an alternative way. This piece shows an interesting connection between sound art and music, because the art under the category of sound art simply does not make sound. I admire this aspect of the piece. I am not sure if many algorithms were used directly in this piece, but Marclay worked with a team of animators in Adobe After Effects.

My process for this project was based on a previous drawing I have done with cacti. To me, these are significant structures because they exist in some isolation from each other by their spread and spacing in the desert, away from clusters of other living organisms, so their visual existence is very extraordinary. To create the cacti in p5, I started with creating a curve shape as the base of the cactus. Then, I randomized the number of arms present on the cactus’s body, where I had to play around with trial and error in creating a curve shape which looked like a cactus arm, but also that was attached to the cactus’s main body. I then, played with creating other objects like the smaller, darker cactus and its visual randomization and its positioning on the second horizon line lower than the first, larger, lighter cactus which was on the first horizon line.

Work from Home

by Hanski aka Hannah Epstein

http://hannahness.com/work-from-home

Work from home was an interactive walk in installation. Users would use their phones to text short code to a number which then triggered a response on the participant’s phone. Hannah Epstein was a MFA candidate at Carnegie Mellon and TA’d one of my sculpture classes. Her work uses humor as means of expression in reflecting serious topics and consists mainly of rug-hooking, a type of soft sculpture, and video games. It was inspiring to hear her talk about her games and how she exists in the field because before, gaming in my mind belonged only to an audience and to creators of men.

Sheenu-Looking Outwards-09

I enjoyed reading this blog post and learning about how artists are implementing their interactive, non-gallery work in public settings. I think that the gesture of flipping the plates in relation to the movement of water and downward movement of the eye is very clever. It creates the illusion of the fountain while also allowing more innovative room for the shape of the fountain, the movement of the water, the scale and closeness of the viewer to the work, and the interaction which initiates a change in the piece. I think especially with our most previous project, this work is relevant to expanding beyond the combination of code with two-dimensional visuals.

I liked playing with opacity in the shapes we make in class. I think the randomization of pixels along with the overlapping of the colors is nice.

Eric Fischer

https://www.mapbox.com/about/team/eric-fischer/

Eric Fischer describes himself as a data artist and software developer, and he is based in the California bay area. His work uses data points of crime rates, traffic, transit lines, race, etc. to map the US. He said his obsession for the past few years is “what makes cities walkable.” His process consists of him carrying a GPS and first personally observing the area he is in and trying to match his walking life with what the retrospective walkability of the area is. From his personal investigations of cities, he has made art about large scale issues in the critiques of those cities, making viewers step back both physically and metaphorically. His presentation was not the most captivating, but with visuals and realistic trends I found it to be very successful. I admire the point he made about how data visualization does net necessarily have to be abstract, and that the ideas behind his work do not end up being abstract. His research thus becomes more than a realization on paper.
