Dreamachine · Images with the eyes closed

Dreamachine, Gysin and Sommerville’s light artwork from around 1960–61, seen with eyes closed so the images arise in the viewer’s perception.

Brion Gysin and Ian Sommerville developed Dreamachine around 1960–61: a light-based artwork meant to be experienced with the eyes closed, so its images arise in the viewer’s perception rather than on a screen. William S. Burroughs belongs to its experimental literary circle; the credited co-creators are Gysin and Sommerville. The overlap here is between an engineered object, artistic intention and a private visual experience.

The photograph shows a later example from 2005. The original artwork uses flickering light; this page shows a still photograph. No therapeutic or paranormal claim is made.

Very Nervous System · The room answers your movement

Rokeby’s interactive artwork turns movement into music, and his 1995 account describes feedback that feels meaningful but is not easy to control.

David Rokeby uses cameras, processing and sound to turn bodily movement into a musical response: you move, hear what happens, and move again. In his 1995 account, Rokeby describes a system that can feel meaningful without being easy to control completely. It makes feedback felt through the body, a useful artistic companion to questions about agency.

An interactive artwork and an artist’s account, not a demonstration of machine consciousness.

Microphones · A voice left by someone else

Lozano-Hemmer’s 2008 microphones that may answer with a previous visitor’s recorded voice; the mechanism is stored sound, yet it seems to remember.

Rafael Lozano-Hemmer’s modified microphones can answer with a recording left by an earlier visitor. Sometimes the speaker hears their own newly recorded voice instead. The object seems to remember: another person’s contribution returns in a later encounter. The mechanism is stored sound and selection, giving an ordinary microphone a gently uncanny sense of history.

Pablo Amaringo · Giving a vision a visible form

Pablo Amaringo’s detailed paintings of Amazonian landscapes and visionary imagery, read as art, not as verification of the worlds they depict.

Amaringo’s detailed paintings bring Amazonian landscapes and visionary imagery into a shared visual space. The ACA catalogue lets us follow his work through named paintings, not as anonymous psychedelic motifs. In the Hancock–Michels conversation, Hancock recalls Amaringo describing painted craft as vehicles between realities. That recollection belongs to Hancock; the paintings are works of art, not independent verification of the worlds they depict.

The interview passage begins around 0:40. The portrait is licensed; use the gallery link to view the paintings in their original context.

Jimena Canales · The beings inside a thought experiment

In Bedeviled, Canales follows notional beings such as the demons associated with Descartes, Laplace and Maxwell: imagination at work, not reported experience.

What can an imaginary observer help us think through? In Bedeviled, Canales follows notional beings used to explore scientific problems, including the demons associated with Descartes, Laplace and Maxwell. Her free publisher excerpt offers a different kind of strange encounter: an invented agent with a defined role in an argument. It makes a useful companion to visionary art, while keeping imagination, reported experience and experimental evidence distinct.

Read the free excerpt, not a paywalled full-book link. The illustration is an editorial motif, not a portrait or a scientific diagram.

The blue seaweed book made without a camera

Anna Atkins placed algae against light-sensitive paper to make a pioneering book of botanical photographs, one blue print at a time.

Added 2026-10-22 · Daily discovery

A spray of pale seaweed rests against a deep blue page. Its branches are delicate, but the image was not drawn. Anna Atkins made this kind of botanical photograph by putting the specimen itself against light-sensitive paper. The plant blocked part of the light, leaving a pale impression on a blue ground. A camera was unnecessary.

In 1843, Atkins began issuing Photographs of British Algae: Cyanotype Impressions in parts. The Metropolitan Museum of Art identifies it as the first book both printed and illustrated photographically. Its specimens came from her own collecting and exchanges with other amateur scientists. For their names she followed William Harvey’s 1841 Manual of British Algae, an unillustrated book, and labelled her plates by hand.

The process was new: John Herschel had invented cyanotype in 1842. Atkins used it to record the forms of algae, arranging their strands across individual sheets. The Met explicitly describes a meeting of science and art in these compositions, while noting that artistic expression was not her chief purpose. That connection belongs to the museum’s account of the work; it does not depend on a modern theory about what the images resemble.

The labour behind the blue pages was substantial. The Natural History Museum reports that Atkins made every print herself and that its copies contain 411 plates. Even the book’s text pages and captions reproduce her handwriting photographically. The museum also places her work within a network of scientific education, acquaintances and exchanges, rather than presenting her as an isolated inventor.

Start with the Met’s album record for the project’s history, then its separate record for Dictyota dichotoma, dated around 1853. The reproduced page shows the seaweed spread across the centre, with its name beneath it. The Natural History Museum’s longer account follows Atkins from botanical illustration into photography, explaining how these small, directly printed specimens became an unusually blue book.
