I recently heard about Color Commons, an interactive public artwork created by New American Public Art. The idea is to allow the public to change the color of the Boston Greenway Light Blades via text message. You simply send an SMS to the Light Blades number (917.525.2337) that says what color you want the lights to be and within about 1 second, the lights will change.
I think this is an awesome project on several different levels. First is the element of interactivity – I really like art that engages viewers beyond a passive consumption level. I also think that the creativity and diversity of perspective embodied by “the public” can discover and create really interesting usage scenarios that the original artist would never have thought of (perhaps this just betrays a lack of confidence in my own creativity and artistic vision but nevertheless…).
It is also interesting to learn more about how the project was executed from an engineering perspective. The creators have generously published their source code and other details about their implementation to help inspire others – check out their project page here. In short, they used a Rascal MCU that runs Python and has a built-in web server and linked that module to a server, which they connected to Twilio to receive the text messages. When a message comes in, they parse it using a Python script to determine which color is being requested and then send the command to the Light Blades controller (a Color Kinetics iPlayer3 with ColorPlay software).
I love seeing this kind of project and hope it inspires others to create interactive art. Hopefully one of these days Pocobor will have time to put together one of the ideas that have been rattling around the office lately…
