For the longest time listening to music and particularly music by FSOL, I've come to associate sounds with visual patterns.
There's a certain Autechre literal music video out there which has motivated me to create a few pieces based on FSOL.
While it's not really synesthesia taking place, I prefer to call videos of this kind "synesthetics."
Figure it's only right I share these with other FSOL diehards. Here are the ones I've made:
It's My Mind That Works
Is This Real?
Ill Flower
Audio-Visuals
Re: Audio-Visuals
I use Blender, and occasionally Audacity to try analyzing those rapid-succession sounds.
