Raspberry Pi Art Frame using OpenFrame

Digital picture frames were a fad awhile back, and you can still pick them up at the local big box store. [Ishac Bertran] and [Jonathan Wohl] decided to go open source with digital frames and create the openframe project. The open-source project uses a Raspberry Pi with WiFi and either an HDMI monitor or a monitor that the Pi can drive (e.g., a VGA with an HDMI adapter).

You are probably thinking: Why not just let the Pi display images? The benefit of openframe is you can remotely manage your frames at the openframe.io site. You can push images, websites (like Hackaday.com) or shaders out to any of your frames. You can also draw on public streams of artwork posted by other users.

Raindrops On An Oscilloscope

Something very beautiful appeared in our feed this evening, something that has to be shared. [Duncan Malashock] has created an animation of raindrops creating ripples. Very pretty, you might say, but where’s the hack? The answer is, he’s done it as a piece of vector display work on an oscilloscope.

He’s using [Trammell Hudson’s] V.st Teensy-powered vector graphics board. We’ve featured this board before, but then it was playing vector games rather than today’s piece of artwork. The ‘scope in question is slightly unusual, a Leader LBO-51, a device optimized for vector work rather than the general purpose ‘scopes we might be used to. The artwork is written using Processing, and all the code is available in a GitHub repository.

So sit back and enjoy the artwork unfolding in the video. We look forward to more work featuring this hardware.

LED artwork disappears right before your eyes

take_a_picture_demo

If you walked into an art gallery and saw nothing but blank canvases lining the wall, you might be compelled to demand your money back, or assume that you had discovered the world’s laziest artist. If this gallery happened to be displaying work by [Brad Blucher and Kyle Clements] however, you would be mistaken.

These two artists have collaborated to create a series of works titled, “Take a Picture“. Each picture they have built is constructed to look like an empty canvas when viewed with the naked eye. If you were to take a picture of the canvas with your cell phone or digital camera however, a whole new world would open up in front of your eyes. Their artwork is constructed using infrared LEDs, which cannot be seen with the naked eye, but are visible to nearly any CMOS or CCD sensor on the market. The images range from simple smiley faces and objects to abstract geometric shapes.

It’s a very simple, yet novel approach, and we happen to think it’s pretty cool. The artists have not said what they have planned for this project in the future, but we’d love to see it expanded using larger LED arrays to display higher-resolution images, or even short movies.

Keep reading to see how they went about creating these works of art as well as a promo video demonstrating the effect.

Creepy robot eye follows you and winks in response


Opto-Isolator is an interesting art installation that was on display at the Bitforms Gallery in NYC. This single movement-tracking eye creates a statement about how we view art and is a response to the question “what if art could view us?”. The somewhat creepy display not only follows the person viewing it, but mimics blinks a second later and averts its gaze if eye contact is kept up for too long. Its creators [Golan Levin] and [Greg Baltus] have done a great job mimicking human behavior with such a simple element and the social implications of it are truly fascinating.

If they wanted to, [Levin] and [Baltus] could possibly crank up the spook factor by adding facial recognition and programming it to remember how certain people interact with it, then tailor its behavior to wink at different rates or become more shy or bold, depending on the personality of the person watching it. Of course, that would require that someone goes back to it more than once…

Making art with Javascript

Mozilla coder [Aza] is connected to the past and the present: he wanted to celebrate the release of Firefox 3, but pines for the days when one could use small amounts of code to make compelling art. As a way of addressing both things, he has released ContextFree.js, a javascript port of [Chris Coyne]’s Context Free Art. Users can visit Algorithm Ink, where they can draw various compelling designs with just a few lines of script. ContextFree.js compiles the scripts and turns them into visually arresting geometric designs. Users can also browse through designs made by others, easily save them as JPGs, or even modify them by adding their own bits of code. What’s more, it’s not out of the question to use this to generate random images on a website, creating a unique visual experience for every single visitor. You all know what we want to see, though: JavaScript gurus working some real magic with this. Better yet, said gurus can play around with the core open-source code and make something truly their own on the most fundamental level. Definitely check out the video above to get an idea of how easy this is.
