Heckenlights is an interactive Christmas lights installation that can be controlled online by just visiting heckenlights.org. Heckenlights consists of over 3000 LED lights that are controlled via MIDI in 12 tracks. Each MIDI note switches the lights on and off.

It all started in 2012 with the idea to control a Relay with MIDI and lead to what it is today. Now, this season is the last one for Heckenlights. It’s been a great fun building Heckenlights and even more stepping outside, opening heckenlights.org on a smartphone and triggering the lights to play.

I’m moving next year to a new house. Heckenlights (originating from Heckenpfad, the address I live) is no more appropriate then.

You can see and operate Heckenlights until Jan 6th, 2017 between 5 pm and 10 pm (CET). After that date, it will be shut down.
