From dusk till dawn

2019

195x95x11 cm / 76.8x37.4x4.3 inches

White diffused acrylic with integrated computer-controlled LED, magenta fluorine acrylic on the back

This work simulates an entire day the electromagnetic spectrum, time, light and space. It shows sunrise and sunset at the equator when the sun is exactly perpendicular to the equator. In this case Volcán Wolf, Galápagos Islands in Ecuador September 23, 2019. The sun rises at 05:57 a.m. in the east at 90° in 100% pure red. Time passes by and color/light gradually changes throughout the day to orange and yellow. We see pure white light at the moment the sun is at solar noon at 11:57 a.m. in the south at 180°/0°. Adding all three primary colors together yields white. 100% pure red, green and blue. White light is regarding to the visible spectrum and the color temperature equal to the green wavelength. The complementary color of white and green is black and magenta. Magenta doesn’t correspond to a wavelength on the visible spectrum. Magenta is an extra-spectral color. It's like you look at a globe and can’t see the back. It’s in another dimension. The sun sets at 06:00 p.m. in the west at 270°/-90°, 100% pure blue. Solar midnight is at 11:57 p.m. in the north at 360°/180°. The back of the work is magenta fluorine acrylic. 'From dusk till dawn' simulates day and night how humanity experiences it.

Time goes very slowly. What exactly happens between sunset and sunrise? Does the sun rise exactly at the same place every day and does it set in the same place? Or does it save a yoctosecond? A fraction of a second that we cannot comprehend?

This work includes an extra program Caroline Atoll September 25. Caroline Atoll is best known for being the first place (since 1994) on Earth to receive sunlight each day during much of the year. Caroline Island in Kiribati is in the middle of the Ring of Fire. The Pacific Ring of Fire is a belt of oceanic trenches, island arcs, volcanic mountain ranges and plate movements that encircles the basin of the Pacific Ocean. The ring is home to 90% of the world's earthquakes.

 

During the exhibition it was possible to scan two qr codes to give visitors a better understanding of my art project. The 'blue' one showed pictures of endemic animal species (galapagosconservation.org.uk), who lives all in harmony at the Galápagos Islands. The 'magenta' one showed destruction of nature in the ring of fire ánd one endemic bird 'the fruit dove' magenta colored on its head. Did the fruit dove survived because its enemies can see magenta, leaving the fruit dove out of sight?

 

'From dusk till dawn' has been exhibited at BIG ART 2019 curated by Anne van der Zwaag and PAN Amsterdam 2019.

#0100ff - #ff0001

2019

195x95x11 cm / 76.8x37.4x4.3 inches

White diffused acrylic with integrated computer-controlled LED, magenta fluorine acrylic on the back

This work simulates extra-spectral colors like crimson, bright pink, magenta and purple. These colors doesn’t correspond to a wavelength on the visible spectrum and are located between red and blue, between the Hex color codes: #0100ff and #ff0001.

 

#0100ff - #ff0001 has been exhibited at PAN Amsterdam 2019 Rademakers Gallery.

Reality

2019

95x95x11 cm / 37.4x37.4x4.3 inches

White diffused acrylic with integrated computer-controlled LED, magenta fluorine acrylic on the back

'Reality' simulates the electromagnetic spectrum, time, light and space when the sun is exactly perpendicular to the equator, it shows day and night. 'Reality' is the sum or aggregate of all that is real or existent, as opposed to that which is only imaginary. 'Reality' is the totality of the universe, known and unknown.

Circadian rhythms

2019

195x95x11 cm / 76.8x37.4x4.3 inches

White diffused acrylic with integrated computer-controlled LED, magenta fluorine acrylic on the back

'Circadian rhythms' mimics daylight. 2000 - 9000 Kelvin. Timing is everything. People, plants and animals all have circadian rhythms.

Black body

White diffused acrylic with integrated computer-controlled LED, magenta fluorine acrylic on the back

'Black body' shows the color temperature of a light source for white light which is defined as the temperature of a hypothetical black body whose emitted light gives the same color impression as the light source and usually expressed in Kelvin. For colors based on black-body theory, blue occurs at higher temperatures, whereas red occurs at lower temperatures. This is the opposite of the cultural associations attributed to colors, in which red is hot, and blue is cold, it is the color temperature of lamps which makes them visually warm, neutral or cool.

Eye of kingfisher

2018

210x150 cm / 83x59 inches

Waterjet cutted metal, both sides powder coated in midnight blue

'Eye of kingfisher' hangs 1 cm from the wall and is about the ever-changing light. While the sun (or the earth to the sun) revolves during the day, the drop shadow changes to different shades. In the morning the shade is light gray and during the day it's getting darker and darker. During civil twilight, when the sun is up to 6 degrees below the horizon, the shade changes to a blue purplish hue. When the sun drops further to 12 degrees and the nautical twilight occurs, the drop shadow becomes dark gray. At astronomical twilight, when the geometric center of the sun is 18 degrees below the horizon, the shadow is almost black. Remarkable about the kingfisher is that he prefers to live in shady areas, where he is not hindered by reflection of light when hunting. He has a predominantly blue color, with iridescent feathers on head and wings and his belly side is warm orange colored as if at certain times of the day in certain sunlight he can always look different for his prey.

 

'Eye of kingfisher' has been exhibited at OBJECT Rotterdam 2018 curated by Anne van der Zwaag.

It's now part of the Bas Kuiper Collection.

Oak branch

2017

350x200 cm / 137.8x78.74 inches

Waterjet cutted metal, orange organic fluorine spray-painted on the back

'Oak branch' hangs 1 cm from the wall. The work changes during the day due to the light. In addition to the different colors of drop shadow, the organic fluorine reflects in orange on the wall.

 

'Oak branch' is commissioned.
