In its passive state, the artwork uses information from the Google Push Notification APIs to find out the rate of communication between people in real time. The artwork only uses information from "human to human communication" applications, such as Google hangout, Gmail etc. This data is then translated to heat through metal rods embedded in the heat reactive glass structure. For instance, the faster push notifications get opened, the higher the communication rate is, therefore the more heat is produced. Inversely, at night push notifications stack up, untouched for many hours. This translates itself to a low communication rate and therefore less visual activity or colder tones. 

In its active state, the artwork becomes collaborative. To be switched to its active state it requires both a Google employee and a passerby below, to touch their respective heat sensors. This action then overwrites the passive mode, and sends a signal requesting maximum temperature -- rewarding physical interaction between strangers. The interaction ends as soon as either participant removes their hand from the heat sensor.
