To visualise how the Slow Screen works we had to sometimes speed up the footage by 800 percent.

It was a difficult place to be for Zurich's Museum of Digital Art
Being already in construction and realising that there is the need to control the
amount of daylight coming into the museum. Some exhibitions need to be dark, some require daylight.
And, being a non-profit organisation, having almost no funds to tackle this problem.
The first working prototype, built with "pixels" made from cardboard and filled with rice to simulate the final weight.
With that in mind we came up with an idea which, to be honest, might sound a bit crazy at first.
That idea was to build a massive screen made from 805 physical pixels, weighing over a ton
and stretching over 100 square metres,
and develop a system to rotate each of the mechanical pixels in order to
regulate and diffuse the light that comes through the screen. This would also
allow the museum to use this large screen to communicate short messages.
Installing and wiring all 115 motors.
Doing it the Chinese way: low budgets, but time and many hands.
Assembling the 805 pixels stretching over the ten large windows of the ground floor of
Zurich's oldest high-rise with the use of four production lines.
To pull this off it was necessary to come up with a very simple mechanic that needs
little resources to control this many mechanical elements. Which meant that to use one motor per
pixel wasn't an option. So we invented a system which can position multiple
a row with only one motor.
By alternating the direction of rotation, positioning each pixel starting with the lowest pixel
of each row and then working its way up.
The trade-off was speed, each physical pixel had to be positioned one after the other, resulting
in a frame rate of about ten images per hour – a neat feature in times where
digital contents are consumed like fast food.
The Slow Screen, taking over the entire front of the ground floor.
The other way to make the Slow Screen possible was to execute this project the way we've learned
from our Chinese business parters: Having a long time line – which
allows that people work on it in between other jobs – to keep costs down. And including friends, family and the entire staff
of the museum to assemble the screen. Having to install 805 individual pixels
takes a lot of time, but if you have many hands it can be done in a couple of days.
The finished Slow Screen.
Once we had the basics sorted we teamed up with the talented Thibault Brevet
and the experts of local engineering company Greenliff
Together, and with the help of many others, we designed, planned and pre-manufactured the
the Slow Screen over several month and assembled it during one week, while the museum was closed.
