Chasing Double Rainbows (www.chasingdoublerainbows.com) visualizes the ephemeral phenomena known as double rainbows by mapping geo-tagged photographs posted to Instagram in the previous 24 hours. The visualization connects users who witnessed a double rainbow closest in time to each other by drawing a rainbow arc between each sequential sighting.
The visualization was inspired by a YouTube video by Paul “Bear” Vasquez whose effervescent euphoria for double rainbows captured the world. Today, Paul's video has over 40 million views. Chasing Double Rainbows is neither a scientific, nor serious visualization, but a facetious data art project celebrating the universal fascination created by the sighting of a double rainbow.
Instagram has over 350,000 public photographs tagged #doublerainbow. In a given 24-hour period, depending on rainy weather conditions world-wide and luck, Chasing Double Rainbows visualizes anywhere between 30 – 300 geo-tagged photographs.
A double rainbow is an optical illusion in which two rainbows are seen. The illusion is created by the reflection of two rainbows in a rain droplet.
A physical map visualizes real time data and was made using plexiglass, wood and cardboard. The continent where the most recent double rainbow was sighted is lit using neopixel leds.
