This summer in Kelowna, the Keloha Volcano came to life.

Twitter Volcano

The chicken wire and painted foam volcano listened to the Twittersphere for any tweets marked #keloha and responded with a tweet and 30 seconds of bubbly fun. A Raspberry Pi running a Node.js program triggered a relay to turn on a bubble machine that I picked up from Walmart. Seemed like it was a hit.

Volcano!
