A Blind Teacher Using Echolocation to Navigate the World

10:53 Add Comment

Echo is a fascinating and poignant short film about Daniel Kish, a blind man who uses echolocation to move about in the world and teaches others how to do the same. Using clicks, he and his students can go on hikes, ride bikes, and skateboard down the sidewalk.

If I click at a surface, it answers back. It’s like asking a question: what are you and where are you? I can get through echolocation a really rich, palpable, satisfying, 3-dimensional, fuzzy geometry.

The filmmakers worked with Kish to record the sound as a person would hear it in real life and make visualizations to help us see what Kish is hearing.

During the early production stages of the filmmakers Ben Wolin and Michael Minahan’s short documentary, “Echo,” they wanted their audience to understand what this skill truly meant. They worked closely with Daniel, a self-described audiophile, to record sound for the documentary through a special microphone that works similarly to a pair of human ears — a tool that Daniel also uses for teaching. “You record the audio like you would hear it,” Minahan told me. Because of this process, the sound design and auditory experience has a vivid, spatial quality that’s rare with a film of this scale. The gears on Daniel’s bike creak and whine with a closeness that makes it feel like we’re riding right next to him, while dogs bark, wind blows, and cars pass in the background. It’s through these rich sounds that we’re immersed in and transported to Daniel’s world.

Make some time for this short film…it’s really great.

NASA: The Ingenuity Helicopter’s Mission Comes to an End

the Ingenuity helicopter on the surfce of Mars

NASA has announced that the mission of the Ingenuity helicopter has come to an end on the surface of Mars.

While the helicopter remains upright and in communication with ground controllers, imagery of its Jan. 18 flight sent to Earth this week indicates one or more of its rotor blades sustained damage during landing and it is no longer capable of flight.

Originally designed as a technology demonstration to perform up to five experimental test flights over 30 days, the first aircraft on another world operated from the Martian surface for almost three years, performed 72 flights, and flew more than 14 times farther than planned while logging more than two hours of total flight time.

Nice job, little flying rover! Rest well.

I Miscarried in Texas. My Doctors Put Abortion Law First. “No one should have to fear they may die because of a miscarriage. And yet, for women like me in the United States, in Texas, that fear is very real.” Repressive, punitive, and sickening.

Therapy Gecko: The Internet’s Unofficial Therapist

15:53 Add Comment

During the pandemic, Lyle Drescher started dressing up as a gecko and doing a live call-in show as Lyle the Therapy Gecko. Drescher is obviously not a therapist (more like an advice columnist?) but he does seem like a generous listener, which is a bit of a rarity online. This video is also a meditation about online identity and the unusual sort of performance art that is familiar to anyone who publishes online (even those of us who work in text & links). (via waxy)
