As part of the residency at iMAL, we plan to work with wind-driven artworks along the channel. To get started, we installed today a 8-led display that uses light persistency to display different stuff.
The "windmills" run at around 1.5 turns per second at mid-speed. We needed to test if that was fast enough to get a visible result. We thus hijacked Yves' bike (for which we yet haven't found the key) to make some tests.
And it worked. Look at the results. Beautiful.
