Thirty Million Pixels, and None

No. 0175 Nov 2026Light · Space · Spectacle

This week: a 42-metre stadium screen that counts every pixel, eleven metres of light tunnel lined with a mirror, a laser performance with no one on stage, and two installations to see.

Bad Bunny's Debí Tirar Más Fotos tour carries one LED screen across the back of a stadium stage: 42 metres wide, 11 high, 10,752 by 2,816 pixels, built from 462 INFiLED Black Widow AMT panels. TPi prints those numbers from Brompton Technology's account of the tour. They check against each other. Multiply 42 by 11 and you get 462, so the screen is one panel per square metre, and 30,277,632 pixels across 462 panels is exactly 65,536 each. The part we would not have guessed is where the picture comes from. More than 90 per cent of the show is cinema-camera footage, and the panels were chosen by the artist, in a shootout between LED products, during a residency in Puerto Rico.

Editorial

Thirty Million Pixels, and None

The screen in the Lead is a count. Thirty million pixels, each one assigned to a panel, each panel to a processor, each processor to a feed. Every decision that matters on that wall can be written as a number, and the people who built it did exactly that.

Robert Henke's FIRST LIGHT, at the Barbican on Saturday, is the other kind of image. Henke describes his laser graphics as "a very narrow focused beam of light, drawing shapes on a screen by precisely moving mechanical mirrors". There is no grid to count, so every decision moves into the software, where Henke has been building since 2020. One show leaves nothing about the picture to chance between the camera and the panel; the other takes the performer off the stage altogether. In both, the audience looks at the result and never at the decision.

Sabine Marcelis, whose first museum show opened in Zurich on 30 October, takes a third route: 125 lamps and one mirror wall make an eleven-metre walkable tunnel. You see twice the lamps the museum bought.

None of them is better than the others. The claim is only that 30,277,632 is not the same as the moment that stops a stadium. None of the three counts that.

Sabine Marcelis built an eleven-metre light tunnel out of 125 lamps and one mirror

Zurich, 30 October 2026 to 4 April 2027, at the Toni-Areal. The museum calls this "Marcelis's first museum exhibition", combining "central groups of works from recent years with site-specific light works". Two rooms do the same thing: a mirror multiplies a lamp count, and the museum prints the count each time.

The VARMBLIXT tunnel is 125 lamps: "eine Installation aus 125 Leuchten, die durch eine Spiegelwand mit Farbverlauf zu einem elf Meter langen, begehbaren Lichttunnel wird." One wall of lamps, one mirror wall carrying a colour gradient. In the installation view the real wall reads yellow and the mirrored one reads red. That is the gradient earning its keep. The two sides of the corridor are not the same colour, so the mirror never announces itself as a mirror. The lamps come from VARMBLIXT, a collection of about 20 objects Marcelis developed with IKEA.

The Mathmos room does it again with a smaller number: "aus acht Leuchten und Spiegelwänden", eight lamps and mirrored walls, in a room that "dehnt sich … scheinbar ins Unendliche aus" — appears to stretch to infinity. Eight. The lamp itself, from what the museum calls a longstanding collaboration with Mathmos, is "fast drei Meter hoch", almost three metres tall.

Our read:

The museum says the 125 lamps become an eleven-metre tunnel "durch eine Spiegelwand", without saying whether the mirror doubles the corridor's length or simply gives a wall of lamps its second side. The installation view shows it running along the corridor, which is the second reading, so we are not claiming the mirror fakes half the length. Either way you walk past twice the lamps that were bought. The museum publishes the count, and a show willing to tell you it is eight lamps is making the mechanism the subject.

Robert Henke is putting no one on stage and running the lasers from the audience

FIRST LIGHT has its world premiere at the Barbican on Saturday 7 November at 20:30, "roughly 75 mins long, with no interval", with "lasers, haze and strobe". Henke's page is plain about the staging: "For FIRST LIGHT, no one is present on stage." Henke himself, the page says, "is controlling the machinery from within the audience, part facilitator, part observer."

The machinery is FirstLightEngine, "a laser graphics software developed since 2020 by Robert Henke, based on MaxMSP", driving laser projectors from LaserAnimation Sollinger Berlin, with additional laser graphics programming by Jonas Margraf.

Two of the five pictures Henke publishes are worth a second look, because the apparatus is in the frame with the image: below the drawn light in both, at desk height, sits a screen carrying the running software. Neither is dated, and neither shows the Barbican, but the arrangement is the one the piece describes — no stage, no figure, a desk in the dark under the thing it is drawing. In the colour frame the lines break into dashes, which is the beam blanking as it crosses the gaps between the parts of a shape.

The one captioned picture, the FirstLightEngine screenshot, is the nearest thing to a plan anyone has published. It shows eight VectorEngine instances, each reporting its own frame rate and point count. A Laser Settings panel carries per-laser gain, rotation, pan, tilt and clipping. A colour calibration table holds serial numbers in four of its eight laser slots. Timing is exposed down to mirror delay, blank speed, line speed and the wait after each polygon corner, which is the real cost of drawing with a beam: everything is drawn by moving mirrors, so every shape is a schedule. What it cannot show is the Barbican rig.

The Barbican prints a dedication: the work "is dedicated to the female astronomers, astrophysicists, engineers, computer scientists, and mathematicians who contributed so much to our knowledge of the universe, yet often enough did not get the recognition they deserve."
