[Orson Scott Card] once wrote “…time flows through all lives equally.” You have to wonder what he would think if he saw Rhei, a fluid clock that is part prototype, part dynamic installation, and part moving sculpture. The developers [Damjan Stanković], and [Marko Pavlović] say that time flows, and thanks to the fluid-based numerals on the clock face, that seems to be an appropriate tag line (if you can’t visualize it, check out the video below).
It is not usually too difficult to separate functionality from art. Consider a clock. It’s a machine that has a clear and distinct function. It provides information. Nothing could be more different from a clock on a wall than a piece of artwork. A painting, for instance has no clear function and provides no information. It’s just…art. It’s nice to look at. If we were to ask you to build a functioning, information providing clock that is also a piece of artwork, you would surely have your hands full. Where would you even start? If your name was [Zelf Koelma], you’d grab a bottle of ferrofluid and build us a beautiful, almost mesmerizing clock.
There’s little to no information on the details of how the clock works other than the use of ferrofluid. But it’s not hard to guess that it uses dozens of electromagnets
and an Arduino. You can even pick one up for a cool $8,300 if you’re lucky enough to get a spot on the list, as he’s only making 24 of them.
Want to make one of your own? Pick up some ferrofluid and keep us updated. We’d love to hear from you in the comments on how you’d implement a build like this one. We had a fun time hearing your ideas when we covered the clock made of clocks.
Moscow artist [Dmitry Morozov] makes phenomenal geek-art. (That’s not disrespect — rather the highest praise.) And with Solaris, he’s done it again.
The piece itself looks like something out of a sci-fi or horror movie. Organic black forms coalesce and fade away underneath a glowing pool of green fluid. (Is it antifreeze?) On deeper inspection, the blob is moving in correspondence with a spectator’s brain activity. Cool.
You should definitely check out the videos. We love to watch ferrofluid just on its own — watching it bubble up out of a pool of contrasting toxic-green ooze is icing on the cake. Our only wish is that the camera spent more time on the piece itself.
Two minutes into the first video we get a little peek behind the curtain, and of course it’s done with an Arduino, a couple of motors, and a large permanent magnet. Move the motor around with input from an Epoc brain-activity sensor and you’re done. As with all good art, though, the result is significantly greater than the sum of its parts.
The glory days of wardriving are certainly behind us but if you’re still hunting in certain areas for access points you can leave the laptop at home. A homebrew program called Road Dog can turn your PSP into a WiFi search device. You must be able to run custom code to use this app.
Ferrofluid is our friend. But having grown up watching the Terminator and Hellraiser movies we can’t help being a little creeped out by the effects seen in this movie.
Follow along with the NASA astronauts in this 20 minute HD tour of the international space station. It’s a cramped place to live but we can’t help thinking that it looks incredibly clean. After all, where would the dirt come from?
How are your woodworking skills? Can you take a wooden block and turn it on a lathe until you have a lampshade 1/32″ thick? We’d love to see how these are made, but imagine the artist’s reaction when hours of labor are ruined by a minuscule amount of misplaced pressure on a carving tool. Patience, we’ll learn it some day!
This video from the past that is about the future of travel does leave us wondering why our cars don’t have built-in radar for poor visibility? We’ve already realized the rear-view-mirror-tv-picture, but we’re going to need your help before the flying police/fire/ambulance-mobile is a common sight. Oh, the fun of seeing a high-tech push-button selector 3:30 into the video. Perhaps the touch-screen was a bit beyond the vision of the time.
Sometimes you have so many servants you need to find creative things for them to do. Only the most discriminating of the super-rich employ a person whose sole responsibility is to erase and redraw the hands of a clock each minute. This video is obviously a result of the global recession as the live time-keeper has been let go; a looping recording took his job!
Last time we checked in with [Marco Tempest] he was syncing video over multiple iPhones. Now he’s at it again with an augmented reality setup. A camera picks up some IR LEDs in a canvas and translates that into information for a video projector. We’d call this a trick, but it’s certainly not magic.
People tend not to think about the non-Newtonian properties of foodstuffs, but we’re glad at least one person did. When it comes to cornstarch, it’s indeterminate viscosity when mixed with water made it the perfect solution for a pretty neat trick: making a liquid move in reaction to a subwoofer. The unique motion can be attributed to the physical properties of the solution: when enough force is applied quickly, it acts as a solid. Otherwise, it flows like a liquid. The erratic bouncing of the sound waves combined with a little tactile manipulation create varying degrees and speeds of applied pressure, which in turn create a mass of flowing shapes that almost appear to be alive.
We’ve covered weird fluids before, but this is perhaps most similar to SnOil, a game that uses ferrofluids to achieve a similar result. SnOil, however, does not depend of vibrations to create shapes in the fluid, it uses small electromagnets and magnetically charges liquid instead. We love the ordered appearance of the SnOil unit, but the chaotic motion of the cornstarch and it’s non-Newtonian properties make it appear almost otherworldly. We wonder how ferrofluids would react in a situation similar to the cornstarch above, since it would respond to both the vibration and the voice coil’s magnetic field.
