All Our Yesterdays is the thesis of Michelle Chandra as part of her graduate studies at NYU's Interactive Telecommunications Program (ITP).

All Our Yesterdays was a one-woman operation but would not have been possible without the help of many. The responsive front-end template was built out by PSD2HTML. Surya Mattu and Sam Slover provided programming assistance in many office hours over the course of the semester.

Special thanks to CartoDB especially Andrew Hill, Aurelia Moser and Andy Eschbacher, Gabe BC and my thesis group, the staff and faculty at ITP, Gilad Lotan, all my ITP peers especially Clio Davis, Diana Freed, Sheri Manson, Rucha Patwardhan, Justin Restauri, and Batu Sayici, and my parents.

To-morrow, and to-morrow, and to-morrow,
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more: it is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.
-Macbeth, Act V, Scene 5

Technical Implementation

Front-End: HTML5 and CSS3 template. Animations created using JavaScript and jQuery.

Back-End: Node.js Heroku web app for data collection to access Instagram API, node modules included tzwhere for timezone information, and suncalc for sunset and sunrise times.

Except for the front end HTML/CSS template, everything was produced by Michelle Chandra including visual design, data mining, user experience design, content creation, conceptual design, site architecture, map visualizations, programming and research.
