Oscar Murillo’s Frequencies unfolds as a quiet act of collective documentation. For the past decade, the Colombian artist has placed canvas surfaces on school desks across the world, inviting young hands to mark them freely without instruction or constraint. What emerges is not art in the conventional sense but something more intimate: six months of accumulated doodle, sketch, smudge and conscious gesture, each layer a voice joining an invisible chorus.

The process operates as a recording device of sorts, capturing the texture of youth culture in real time. Murillo views each canvas as a data point, a neural map downloaded from an individual mind into a broader network. The red canvas from Argentina, vivid with its naive tower and rainbow emerging from an owl’s beak, speaks to something universal in childhood expression even as it remains radically personal.

For the last six years, the artist has undertaken the meticulous work of digitising every canvas collected from schools worldwide, preserving this fragmented archive of global youth. The endeavour has resulted in a digital repository now accessible online, accompanying his current exhibition Unfinished thinking: Paintings and Social Maps at David Zwirner Paris. The show maps these collected gestures across the globe, a wall text displaying the countries involved; the silver shelving units in the Paris gallery hold hundreds of the originals, their cream grounds and layered marks visible in their delicate, unfinished state.
What makes Frequencies remarkable is its refusal of artistic authorship as singular. Murillo orchestrates the conditions for expression but does not dictate its form. The resulting works belong equally to the hand that held the marker, the classroom culture that shaped the impulse to mark, and the moment in youth when consciousness and play collide. The digital archive extends this generosity, making these intimate documents available to anyone who wishes to observe how young people around the world make meaning through colour and line.
