In fact these LED balloons included the ability to not only transmit messages, but also color changing responses via their embedded LED lights. Human interaction was possible at the light-lined wall, where people could send personalized messages. Although viewing stations and messaging locations were scattered throughout the entire light installation.
This allowed for its participants to create a line of pulsating colors and messages, creating a colorful array of pulsating balloons. What a sight! This light and communications installation was originally a part of last years London 2012 Festival.
