Sketchbook

Hand-drawn visuals on paper: pencil strokes, ink and charcoal that sketch the music as it plays.

Launch modes

Pencil Lines mode

Pencil Lines

Each beat, a pencil draws the waveform out from a graphite knot to both edges of grainy paper.

Ink Doodles mode

Ink Doodles

Doodles fly out of an ink blot on the beat, sprout stroke by stroke and dry from glossy to matt.

Charcoal Rings mode

Charcoal Rings

Rough charcoal rings burst from a smudged core, thicken with the bass and smear as they spread.

Notebook Grid mode

Notebook Grid

A ballpoint bar chart on ruled paper, redrawn bar by bar as a pen sweeps across on the beat.

Scribble Bars mode

Scribble Bars

Mirrored bars coloured in with frantic graphite and red chalk scribbles, re-scribbled by each beat.

Blueprint mode

Blueprint

White drafting on blueprint blue: a part shaped by the spectrum, dimensioned live as it plays.
