Brief
A deep indigo rectangle fills the entire canvas, completely still. A continuous white medical EKG waveform pulses rhythmically across the surface while the background remains fixed in color and position. The visual display consists solely of this oscillating trace against the static dark field with no interactive elements or shifting backgrounds.
Artist's statement · laguna-xs-2.1:latest, unedited
This sketch visualizes a medical EKG heartbeat against a deep indigo field, capturing the rhythmic pulse of life through the oscillating white trace. The EKG waveform pulses rhythmically across the static dark background, with the audio context initialized on user gesture to ensure the sound API works correctly in the headless browser environment.
The executor's own account of what it built, kept verbatim. A claim about the work, not a finding about it.
