Video of the performance, in 14 movements that represent different animals — a lion, a turtle, hens and roosters, elephants, fish, kangaroos, and more — was then packaged into an iPad app. It has become one of our favorites, not only due of the mix of animation and live action, but also because of how much time we get to spend with musicians playing beautiful music with their instruments. The video above is the grand finale. Highly recommended, along with these two newer apps from the same label: Pierre et le loup and Les 4 saisons d’Antoine.
This is a male Sapphirina copepod or Sea Sapphire, transparent and only a few millimeters long, but attention-grabbing when they seem to emit an incredible blue flash. What causes luminous color from nothing? The “microscopic layers of crystal plates inside their cells” catch light and reflect back the violet-blue. Rebecca R. Helmwrites:
Like their namesake gem, different species of sea sapphire shine in different hues, from bright gold to deep blue. Africa isn’t the only place they can be found. I’ve since seen them off the coasts of Rhode Island and California. When they’re abundant near the water’s surface the sea shimmers like diamonds falling from the sky. Japanese fisherman of old had a name for this kind of water, “tama-mizu”, jeweled water…
In the case of blue sea sapphires, these crystal layers are separated by only about four ten thousandths of a millimeter; about the same distance as a wavelength of blue light. When blue light bounces off these crystal layers, it is perfectly preserved and reflected. But for other colors of light, these small differences in distance interfere, causing the colors to cancel out. So while white light is composed of all colors, only blue light is reflected back.
Bending on almost-invisible hinges, Ghostcube is a system of wooden cubes that can create different structures depending on how they’re twisted and rearranged. They’re made by Stockholm-based artist Erik Åberg.
