How it works
How it works
Composed of rotating prisms over two meters tall, Prismatica is an interactive art installation that invites you to spin its iridescent prisms for a luminous and sonic experience.
Each prism is covered with a dichroic filter, a material that reflects different colors depending on the viewing angle and light source.
Each prism contains a chime with a different tone. Move through the installation and spin the prisms to hear a series of melodies harmonize with each other.
Rotate the prisms to see various hues of the light spectrum appear as colorful reflections. Each prism is also illuminated at its center by a spotlight placed in its base, allowing for an equally dynamic experience at night.

Discovery Activities
To each their own perspective!
Choose a prism from the Prismatica installation and stand in front of it.
Now, observe where the light source is coming from.
Have the colors changed with your point of view (angle of observation)?
Step 3
If it’s daytime: where is the sun in the sky? At what angle do the sunrays hit the prism? If it’s nighttime: where is the prism being artificially illuminated from?
Have the colors changed with movement?
Step 1
Look at the prism straight on while standing. Notice the colors you see.
Step 2
Then, squat down and look at the prism from top to bottom. Notice the colors you see.
Step 4
Notice the colors you see depending on the light source and where it comes from as you move around the still prism.
Step 5
Now, spin the prism. What colors appear now?
Step 6
Finally, if it’s daytime: what color is the shadow of the prism on the ground? Is it the same or different from the colors you see on the prism?

GOOD TO KNOW!
Light can be broken down into light waves that are visible to the naked eye: colors.
The colors of the rainbow, ranging from red to violet, each have a different wavelength, which together make up what is called the “light spectrum.” Red has the longest wavelength, and violet the shortest.
Dichroic materials can separate a light beam into two beams with different wavelengths, which creates changing color effects known as iridescence.
The light spectrum
