Espills is a “solid light dynamic sculpture,” made of laser beams, laser scanners, and robotic mirrors. And it makes a real-life effect that would make Tron proud.
The work, made public this month but part of ongoing research, is the creation of multidisciplinary Barcelona-based AV team Playmodes. And while large-scale laser projects are becoming more frequent in audiovisual performance and installation, this one is unique both in that it’s especially expressive and a heavily DIY project. So while dedicated vendors make sophisticated, expensive off-the-shelf solutions, the Playmodes crew went a bit more punk and designed and built many of their own components. That includes robotic mirrors, light drawing tools, synths, scenery, and even the laser modules. They hacked into existing DMX light fixtures, swapping mirrors for lamps. They constructed their own microcontroller solutions for controlling the laser diodes via Artnet and DMX.
And, oh yeah, they have their own visual programming framework, OceaNode, a kind of home-brewed solution for imagining banks of modulation as oscillators, a visual motion synth of sorts.
It’s in-progress, so this is not a Touch Designer rival so much as an interesting homebrew project, but you can toy around with the open source software. (Looks like you might need to do some work to get it to build on your OS of choice.)
Typically, too, visual teams work separately from music artists. But adding to the synesthesia you feel as a result, they coupled laser motion directly to sound, modding their own synth engine with Reaktor. (OceaNode sends control signal to Reaktor via the now-superior OSC implementation in the latter.)
They hacked that synth engine together from Santiago Vilanova’s PolyComb – a beautiful-sounding set of resonating tuned oscillators (didn’t know this one, now playing!):
Oh yeah, and they made a VST plug-in to send OSC from Reaper, so they can automate OSC envelopes using the Reaper timeline.
It’s really beautiful work. You have to notice that the artists making best use of laser tech – see also Robert Henke and Christopher Bauder here in Berlin – are writing some of their own code, in order to gain full control over how the laser behaves.
I think we’ll definitely want to follow this work as it evolves. And if you’re working in similar directions, let us know.
