Feeling the Music

Well, not quite.

But researchers at the University of Tokyo have invented a device which allows you to feel virtual objects by creating a solid wave of ultrasound (yes, the same ultrasound they use in sonograms) which adjusts to the movements of your hand. Currently, this seems to create a tactile field in 3D space that can be felt and interacted with, but, from what I saw it doesn't create 3D objects just yet.

This offers very interesting possibilities for all kinds of computer-based applications. including games, 3D modeling and interactions with the web. Imagine being able to actually, haptically interact with that spaceship you're building in Maya, or feel the design object you're about to buy online. The more dirty-minded amongst us will also see the possibility for a more satisfying pornographic interaction with the web.
It would be interesting to see if they are able to simulate various textures as well, as it would be a great boon to online shops selling, for instance, clothes.
Another interesting possibility is the fabled holographic keyboard of old, allowing you to type and interact with you computer without actually having any devices attached, as the device senses the location of your hand, and supposedly, fingers, thus making it possible to type on thin air.
The title will take to the unis website, where a demo of the Airborne Ultrasound Tactile Display (they may need a new name for it) can also be seen.

Come to think of it, it might also redefine the term "Wall of Sound".

IGAF: Utopia- Les Jours Meilleurs

A couple of weeks ago, I wrote this post, titled Dystopia , containing a dark version of the future, a look at the negative outcomes that might crawl out of the COVID-19 crisis. It has, by now been described as "9/11 in slow motion". Someone else broke a golden editorial rule to describe it as "2008 on crack". Media outlets, including Youtube, have warned of the long-term effects of this, on civil rights, labour and employment, surveillance and press freedom. And some, most notably Mr Orban of Hungary, have used this excellent opportunity to pass new, restrictive legislation that concentrates power in their hands. There have been calls for the elusive COVID cure not to be patented. And yet… And yet… It's easy to lose yourself in a media bubble, following the news and media 24/7, following, queuing in line to get into expensive shops, just walking into discount stores and the constant desire for many drinks (preferably with 10 friends or more, in a park

In Taheyya we Trust - How an Egyptian bellydancer found her posthumous stage in Berlin

“You should have winked at her,” Aida said dismissively, as if such a possibility had been imaginable for someone as timid as I was. Tahia Carioca was the most stunning and long-lived of the Arab world’s Eastern dancers (belly-dancers, as they are called today). Edward Said, Farewell to Taheyya My story with Taheyya begins in the summer of 2016, at Bulbuls Café in Görlitzer Str. in Berlin. It ends two blocks down on Wiener Str 17. Bulbuls is a café and art space around my corner that I have grown to like to sit in and drink smoothies (1). He had commissiond us- a crew of Syrian and Egyptian artists, as well as myself, to paint the walls inside the café. El Tenneen (the Dragon) is the one who ended up drawing Sheikh Imam, with the help of Salam Alhassan (known as Salahef/ Turtles) and Sulafa Hijazis (whom we call El Hayya/The Snake’s) beamers’ illumination. The Sheikh sits happily in the place to this day and Crew El-Zoo was born. Tenneen had the adv

Random Browsing gets me a new face.

Two o'clock in the morning is generally a good time to randomly surf the web and the blogs. This lovely lady, known to me only as Wow Legs, points the blogophere in general to this brilliant Manga face creator . Akin to the Simpsonize me Viral effort, this allows you to create a mangaesque face for yourself, using prefab elements that actually work. Hours of fun to be had here. I think this might be how some tv cartoons are made, right down to the script, except that they don't possess the power of a handsome jawline. Just to clarify: This is Wow Legs manga avatar. Generally, I try not to mangafy people I haven't seen in real life. The picture above is something I threw together as a test. UPDATE: I don't know what happened here, but my clarification seems to have caused more damage than good. As my editorial standards prevent me from knowingly misinforming you, I posted the clarification (above) to do exactly that and not mislead the reader. I also wanted to preserve
