Program in C code, shaped like a donut, renders a 3D donut shape in ASCII, originally put together in 2006 by Andy Sloane:
At its core, it’s a framebuffer and a Z-buffer into which I render pixels. Since it’s just rendering relatively low-resolution ASCII art, I massively cheat. All it does is plot pixels along the surface of the torus at fixed-angle increments, and does it densely enough that the final result looks solid. The “pixels” it plots are ASCII characters corresponding to the illumination value of the surface at each point:
.,-~:;=!*#$@from dimmest to brightest. No raytracing required.
This [$600] USB cable is simply revelatory in its combination of ease and refinement on one hand, and resolution and transparency on the other. Although capable of resolving the finest detail, Diamond USB has a relaxed quality that fosters deep musical involvement.

What a mix - if this doesn’t make you smile then there is something inherently wrong with your soul. RIP Frankie - enjoy your residency on the other side
In that model, our three-dimensional (3D) Universe is a membrane, or brane, that floats through a ‘bulk universe’ that has four spatial dimensions.
Ashfordi’s team realized that if the bulk universe contained its own four-dimensional (4D) stars, some of them could collapse, forming 4D black holes in the same way that massive stars in our Universe do: they explode as supernovae, violently ejecting their outer layers, while their inner layers collapse into a black hole.
In our Universe, a black hole is bounded by a spherical surface called an event horizon. Whereas in ordinary three-dimensional space it takes a two-dimensional object (a surface) to create a boundary inside a black hole, in the bulk universe the event horizon of a 4D black hole would be a 3D object — a shape called a hypersphere. When Afshordi’s team modelled the death of a 4D star, they found that the ejected material would form a 3D brane surrounding that 3D event horizon, and slowly expand.
The authors postulate that the 3D Universe we live in might be just such a brane — and that we detect the brane’s growth as cosmic expansion.

Sand Babel: Solar Powered 3D Printers Building Desert Skyscrapers With Sand
From 3D Print:
Sustainable, green construction in areas where people would never dream about living, is something that 3D printers could one day make possible.
A Chinese team of designers, including Qiu Song, Ren Nuoya, Kang Pengfei, Bai Ying, and Guo Shen designed the Sand Babel Towers, which are a unique concept group of buildings that can be constructed in the desert, with cranes, and 3D printers. The actual design was submitted to eVolo’s 9th Annual Skyscraper Competition, and received an honorable mention. The competition challenged artists, architects, and designers worldwide, to imagine future towers that address a dense, energy and water-scarce world.
FireChat sounds fairly conventional from the get-go. It’s a new iPhone app that lets you chat and share photos with nearby users — anonymously, if you so choose. But instead of relying on global…

Unsure of how to confess your love to someone? Try this:
- Acquire several dozen limes.
- Go up to them and then drop all the limes.
- Start picking them up, but keep dropping them. The clumsier you look the better.
- Keep doing this until you have their attention (this could take up to thirty minutes).
- Finally gather up the limes. Try looking a bit sheepish.
- Look them deeply in the eyes and say, “Sorry. I’m bad at Pickup Limes.”
- Marry them.
Eat Your Tardigrades or You Don’t Get Dessert!
You know this little guy, right? It’s the mighty tardigrade, as featured in the new Cosmos. Tardigrades, also known as water bears, also known as FREAKIN’ MOSS PIGLETS, are microscopic eight-legged animals that can withstand temperatures from near absolute zero to boiling water, absorb extreme doses of radiation, go without food or water for ten years, and even survive the vacuum of space. They can even be completely dried out and ride on the wind to a new home, where they rehydrate and go about their tardibusiness. Tardigrade rain, folks.
In other words, they are BAMFs (bad-ass microfauna).
Oh, and you’ve probably eaten them. Thanks to Meg Lowman, I found out that these water-dwelling super-critters live not only on wild mosses and wet plants, but on grocery store produce like lettuce and spinach. Do you think that a mere rinse or shake under the faucet (or even cooking) is enough to dislodge a radiation-eating space pig? Ha! Not by a long shot, according to Lowman.
So yeah… trying to go strictly vegetarian? You’ve almost certainly eaten some tardigrades. Sorry. Don’t worry, though. They’re totally harmless. I like to imagine that when I eat them, I absorb their power, and become a little bit mightier.
New motto: For strength, eat your vegetables and eat your tardigrades.
Meg Lowman has more about your local tardigrade friends. Also check out Lowman’s awesome research project that helps wheelchair-bound students climb to the top of the forest canopy where they help study tardigrade biodiversity. Science is for everyone!
"…Rialto’s randomised controlled study has seized attention because it offers scientific – and encouraging – findings: after cameras were introduced in February 2012, public complaints against officers plunged 88% compared with the previous 12 months. Officers’ use of force fell by 60%.”
