During the Barcelona Llum light festival 2019, ProtoPixel gave 40 eager creatives the chance to explore new ways of interaction and learn about the ProtoPixel soft- and hardware, while creating unique light installations.

I was one of the lucky participants joining this intense weekend of crafting and light hacking.

Teamed up with 7 inter-disciplinary experts in their fields ranging from data mapping and programming to making, street art and design, we had 16 hours to set-up a working prototype of a wearable.

Concept & Inspiration

Our piece is inspired by traditional Masai adornments, light reflections on textiles and the play of light on volumes of the human body. With the intention to craft a piece of wearable art that would transform the wearers body into a canvas of lights, we went to work.


Being part of the Llum festival of lights, we wanted to directly connect our item to the event, reflect existing and spark new user interaction on Twitter.

An embroidered large round collar with integrated LED strip provides a large enough radius to reflect light onto the entire upper body of the wearer. LEDs are positioned under the brim of the piece, while the upper surface is kept clear to protect the individual from being blinded or distracted.

Connected to the internet via a WIFI controller, the wearable scans Twitter for key words related to the Llum festival. Every time a tweet including the following hashtags or words is posted the wearable changes its lighting patterns to strong blue and red hues in a dynamic rhythm:

Default mode: the slow circular movement of green and pink lights attracts attention yet gives a calm impression.

Tweet detected lighting animation: As soon as a tweet with the right keywords is detected, a strongly contrasting blink appears to signal a new post.

Thanks to everyone all mentors for supporting us during the weekend. Special thanks to my amazing team members and of course ProtoPixel for making this fun and adventurous weekend possible.
