A 3D Printed Sundial Displays Time Like a Digital Clock 

sundial-1

Using a clever mix of 3D printing and a few well-placed shadows, this sundial designed by Mojoptix projects the actual time as if displayed on a digital clock. The plastic component that casts the shadow—called a gnomon— is printed with extremely tiny holes that create pinpoint dots of light in the form of digits as the sun shines through during the day.

The sundial does have its limitations. The time only shows in 20 minute increments and it only works from 10am to 4pm during the day. Regardless, the results are no less miraculous when you see it in use in the video below (skip to around 13:00 to see it in motion).

The completed device is available for purchase here, or you can download the design files and print your own. (via My Modern Met)

Secrets of the Sun: Artist Peter Erskine Transforms Interior Spaces with Laser-Cut Prism Installations

“New Light on Rome 2000”. Aula of Trajan’s Markets, Rome 112 AD, in spectrum sunlight. Materials: sunlight, laser cut prisms.

In the late 1980s American artist Peter Erskine began to incorporate sunlight into his artistic practice through the use of strategically placed laser-cut prisms in both modern and historical sites. A hybrid of both art and architecture, he explores the way light falls on varying surfaces and brings new meaning to existing places. Erskine says the intent of his light installations is to use “the emotional impact of art to address the full range of nature from its most elemental expression as pure light to its most complex expression as global ecology.” You can explore more of his work with light over the last 30 years on his website.

Photographer Unknowingly Captures a Bird Flying into a Solar Eclipse 

eclipse

While standing in her backyard garden this morning around 9:20am in Leicestershire, UK, photographer Amy Shore snapped away at a perfectly clear view of a total solar eclipse with her Nikon D600. What she didn’t know until after the fact was that a lone bird was crossing the viewfinder at just the right moment. Via email Shore mentions that as a full-time photographer she normally shoots weddings, and the split-second decision to take this shot was a happy accident. It’s not immediately clear if there happened to be a weasel riding on the bird.

This eclipse was the first viewable over the UK in the social media age and photos, videos, and accounts like this have spread everywhere since this morning. The Guardian in particular had fantastic minute-to-minute coverage.

Update: Photographer Andrew Brooks got a similar shot in Manchester.

A New Artificial Skylight System Nearly Indistinguishable from the Sun Itself

In what may be one of the most ground-breaking developments in creating artificial sunlight, a group of Italian scientists recently announced CoeLux, a new kind of skylight that perfectly mimics the feel of daylight. The creator’s claim the system is so effective that it tricks unknowing individuals into thinking they are looking up at the actual sun.

The inventors are somewhat tight-lipped about how CoeLux works, but it involves filtering a light source through a layer of nanoparticles that mimic Earth’s atmosphere. Because of this, not only does the color match sunshine but the quality does as well. In the photos above—which CoeLux insists aren’t digitally altered—you can get an idea of how realistic the light is, and see it in action in the video.

The light is currently available in three different configurations that mimic sunlight at different points on the globe including tropical, mediterranean, and nordic environments. Applications for CoeLux might involve anywhere light is scarce, from extreme environments like scientific outposts to underground parking garages or even in hospitals. You can see more on their website. (via PetaPixel)

HD Timelapse of the Sun Captures Largest Sunspot in 22 Years 

The Solar Dynamics Observatory just released this amazing timelapse created from 17,000 images of the sun taken late last month. The bright spot you see gradually passing from right to left is sunspot AR 2192, the largest observed sunspot in 22 years. It measures 80,000 miles across or roughly the width of 10 Earths side by side. Definitely recommend watching it full-screen. (via Kottke)

Amazing Solar Flare Eruptions Captured by NASA’s Solar Dynamics Observatory

This amazing composite image taken by NASA’s Solar Dynamics Observatory (Little SDO) shows a series of significant solar eruptions that occurred over a period of three days back in January of 2013. The photo was created using three wavelengths of light that have been colorized in red, green, and blue to better show the dynamics of each eruption. You can read more about solar scientist Nathalia Alzate’s findings regarding the event over on this Facebook post. (via This Isn’t Happiness)
