I’ve been working on a project called Visualight, an open source wifi connected lightbulb that visualizes data as colored light. It connects to weather, NYC MTA and social networks to displays alerts as colored light. Its also connects to the New York City sewers as part of DontFlushMe to alert people about sewer overflows, like today!

I’ve got a kickstarter going– I’m based in Brooklyn and will hopefully be manufacturing them here too!
