Excerpts from Marcell Marias' live A/V set at Black Rock Equinox 9, a Burners Without Borders Seattle fundraiser. Ableton Live was used for multichannel playback with live filtering, mixing and effects. An additional MIDI track in Live triggered the visuals for the Vortexinator, where Modul8 provided the video signal and Madmapper controlled the RGB LEDs and provided video projection mapping onto the sculpture. All video content and music, including live remixes, produced by Marcell Marias.
The Vortexinator is an interactive LED/Video Projection-mapped sculpture utilizing a modular triangular screen, with RGB and white LEDs. It was installed at Uniting Souls' Deeper Roots night at Substation in Seattle on Aug. 8th, 2015.
My aim as an artist is to break down the barriers between the art and audience. I started this with the Vortexya Video Kaleidoscope, an all analog video feedback machine that allowed the audience to make endless kaleidoscopic patterns with video. vimeo.com/106627224
The Vortexinator is the latest in my interactive series. Design, fabrication, LED integration and projection mapping were done by me. All photography and motion graphics used in the piece are original, with the exception of the Uniting Souls logo.
Gratitude to Ramiro from Uniting Souls for his continued support, and thanks to his wonderful audience for the interaction and kind compliments.
A video documentation of a live audiovisual performance involving original music, video and sculpture by Marcell Marias.
Audio loops and video sequences are triggered in real-time using a 64-button MIDI controller. In Ableton Live 8, each button is mapped to looped stems consisting of drums, bass, synth and effects from the song "Eye". The same buttons are mapped to corresponding snowflake animations in Modul8, which are then video projection-mapped onto the snowflake shapes of the aluminum sculpture.
The resulting performance is improvised and the audio and video is recorded live. It creates a magical interactive piece which glows, moves, and responds to the player's touch. The snowflake shapes originated from photographs taken by Caltech Physicist Kenneth Libbrecht and used by permission. I also animated and effected the snowflake photos in order to achieve all of the imagery that is mapped onto the aluminum shapes.
The original photos are amazing and can be seen at SnowCrystals.com

The project was initially inspired by a number of things including a book, The Art of the Snowflake by Kenneth Libbrecht, video mapping art, and the desire to make an interactive, audiovisual installation.
After being awestruck by the beauty of the photographs in the book, I contacted Kenneth Libbrecht, a Caltech Physicist, and asked for permission to use some of his photos in an art project.
At the same time I was researching video mapping and gained knowledge of the Mapping Festival in Geneva. I saw some amazing installation and performance documentations, which further inspired me to start a video mapping project. I wanted to map complex shapes and the snowflakes were a perfect complement.
Mr. Libbrecht kindly granted me permission to use his snowflake photos and I was on my way to masking and animating them. I also used 3 snowflake shapes to make the 13 aluminum snowflakes which comprise the projection surfaces.
For the sculpture I decided to use aluminum, as it is lightweight and light in color. Modularity was important, so all parts bolt together easily with 1/4" bolts and wing nuts. I incorporated a tripod stand using the two lower legs so it can be freestanding, but I also made two lower legs without extensions so the sculpture can be hung. All the surfaces of the aluminum snowflakes were sanded so it looks like frost grew on them, and the radiating support arms were also sanded.
The snowflake photos were animated in Modul8 and exported as Quicktime movies into After Effects, where corresponding snowflake shapes were used as masks. These movies were then imported into Modul8 and used as the main visual components. A full frame mask of the snowflake array was made and adjusted, vector by vector, as the mask was projecting on the actual sculpture. This mask was used as the main output mask over the animated snowflake layers in Modul8, which then projected onto the snowflake shapes of the sculpture.
The projector I decided to use was a Canon SX50 for its higher 1400x1050 resolution and its fine LCoS panels. This is mounted on a heavy duty Bogen tripod, but can be ceiling-mounted for installation.
My intent from the beginning was to make this an interactive piece, so I incorporated midi-triggering of music sequences along with the video clips. The music used in this video is my song "Eye" from my "Positive Energy Revolution" release. Tracks containing drums, bass, synths, and effects were laid out in Ableton Live and mapped onto buttons of a 64-button MIDI controller. Then the same button mapping was used to control the corresponding snowflake animations in Modul8. This triggering of both music and video clips at the same time makes for a very interactive, immersive and fun display of complex video mapping art.
I hope everyone enjoys this and I wish to share this with as many people as I can. I will also continue to develop other designs, expand upon the interactivity if pieces, and push the boundaries of this exciting art form.
