Women from the Yakama Native American tribe used strings of hemp as personal diaries. Each major event in their life was represented by a knot, a bead or a shell. This mnemonic device is called an Ititamat, or counting-the-days ball, or simply time ball. The first image shows an Ititamat created before 1920. On the second image, each string is a different Ititamat. The last image shows a 2003 replica. A young woman would use a time ball to record her courtship, marriage, and other experiences […]

The object on the left may be one of the first sound sculptures. It appears in a 1960 book by German acoustician and musicologist Fritz Winckel (click on the middle image to see the full page). It is a physical 3D spectrogram showing a frequency analysis of an 8-second recording of Beethoven's Eighth Symphony. The left axis is frequency, the bottom/right axis is time, and the vertical axis is the strength of a particular frequency at a particular time. The figure caption uses the term […]

Slumber was a multi-year gallery installation/performance by artist Janine Antoni. From the website description: Performance with loom, yarn, bed, nightgown, EEG Machine and artist’s REM reading. Antoni transforms the fleeting act of dreaming into a sculptural process. Between 1994 and 2000, the artist slept in the bed while an electroencephalograph machine recorded her eye movement. During the day, Antoni would sit at the loom and weave shreds of her nightgown in the pattern of her REM. The […]

Wafaa Bilal’s brother, Haji, was killed by a missile at a checkpoint in their hometown of Kufa, Iraq in 2004. Bilal feels the pain of both American and Iraqi families who have lost loved ones in the war, but the deaths of Iraqis like his brother are largely invisible to the American public. and Counting… addresses this double standard as Bilal turns his own body — in a 24-hour live performance — into a canvas, his back tattooed with a borderless map of Iraq covered with one dot for each Iraqi […]

Humanity has been gazing at light from distant stars since time immemorial. But in 2015, our ability to understand the University achieved a major milestone, when ripples in Spacetime itself - instead of light - told the tale of an ancient, cataclysmic collision between black holes. The Laser Interferometer Gravitational-Wave Observatory (LIGO) is an experimental system of almost unbelievable sensitivity. Using interferometer arms four kilometers long, it can detect changes in length as tiny as […]

DayDohViz is as a "daily" inspiration project that experiments with physically visualizing data in 3D using a smartphone and Play-Doh. Yes, Play-Doh. Creator Amy Cesal's subjects range from self-disclosing and serious (her personal financial data, government enforcement actions) to delicious and exhilarating (pizza types, top roller coasters). Amy has found the tactile, ephemeral & imprecise nature of Play-Doh - so different from the typical data viz technology - to be creatively […]

Handmade physicalizations of Canada's greenhouse gas emissions, by Mieka West and Sheelagh Carpendale. Each object represents data from a specific year (1990, 2010, and projections to 2030). Initially meant to be smog masks, the designs evolved into strange and beautiful objects evoking indigeneous artefacts such as Native American dreamcatchers, Inca quipus and Polynesian genealogical instruments, and whose visual and material complexity is reminiscent of Nathalie Miebach’s Woven Sculptures. […]

As part of a zoology class, evolutionary biologist Leo Smith created a phylogenetic tree of fishes where each leaf is an actual fish specimen. Source: Leo Smith's tweet (29 April 2018). Related: Also see our other entries on physical visualizations built by re-arranging physical items.

Inequality in Chile represented with LEGO bricks. Made by Harry Lizama, a data scientist in the Ministry of the Environment of Chile. The surface represents the totality of the income. Each person represents a decile. In light green is decile 10. In green is decile 9. In dark green are deciles 7 and 8. In red are deciles 1 to 6. Sources: Harry Lizama, based on data from the Ministry of Social Development, CASEN 2017. Image taken from […]

The mother [of] Sara Weber knitted this scarf during her daily train rides to work in Munich and used different colors depending on train delays. Every day two rows: Grey, less than 5 minutes delay. Pink, 5 to 30 minutes delay. Red, both rides delayed or one more than 30 minutes. The huge red area was during construction work, where the train was substituted by a bus. Side note: The tweet went viral and at the end she sold the scarf at eBay and gave the money to the "Bahnhofsmission" who take […]
