skip a message / skipping messages across the chicago river

Skip Message is a site-specific project developed by Ketai LLC. for LEVEL 13 . LEVEL 13 is a free, five-day, annual architecture and art event that showcases site specific, experimental, interactive installations that embrace Chicago's rich cultural landscape along the Riverwalk—a future site for recreational activities connecting the Lakefront with the heart of downtown. LEVEL 2013 – THIS PROJECT WAS LOCATED AT THE CHICAGO RIVERWALK BETWEEN DEARBORN AND CLARK STREET BRIDGES. The popular pastime of skipping stones serves as the metaphor for this interactive piece, using the dark river surface as a projection canvas. Passers-by engage with the work through their mobile phones via http://ket.ai/skip . A personal message is attached before skipping a virtual stone across the river surface, gesturing the phone accordingly. If the message reaches the other side, it is displayed at this highly frequented public place.

A discursive, location-based work that ties personal presence to an uncensored pubic media outlet, the project investigates freedom of speech and crowd psychology within a ‘post-anonymous’ microblogging context.

I worked with Daniel Sauter and J. Duran in this project. The javascript webpage programming needed to recognize the 'skip' gesture in mobile phones, and the implementation of the messaging infrastructure using RabbitMQ, were my main contributions to this project. Messaging was needed to handle messages from the mobile clients to the server application that was in charge of rendering and projecting the graphics and messages on the river.

technologies used:   rabbitmq, html, css, processing for android, processing+OSC, javascript
