PatterNodes is a procedural design to for creating graphical patterns, animations or illustrations based on repetitions. This is done by defining a sequence of steps that describes the design, using nodes and connections between them. PatterNodes is designed from the start to make it easy to tweak things to see how they turn out. Therefore the resulting design output is always shown in the bottom preview view, repeated for patterns and updating in real time with any changes, giving you instant feedback of what the end result will be.

While the software can be used to create many types of illustrations and animations it's primarily aimed at pattern creation. To make pattern creation easier PatterNodes also includes a lot of nodes that automatically perform common tedious tasks like repeating elements at the tile edges to make the pattern seamless, or randomizing different aspects (like color, position, rotation..) of the elements in a pattern to give it a little more life.

Artificial Neural Networks have spurred remarkable recent progress in image classification and speech recognition. But even though these are very useful tools based on well-known mathematical methods, we actually understand surprisingly little of why certain models work and others don’t. So let’s take a look at some simple techniques for peeking inside these networks.

We train an artificial neural network by showing it millions of training examples and gradually adjusting the network parameters until it gives the classifications we want. The network typically consists of 10-30 stacked layers of artificial neurons. Each image is fed into the input layer, which then talks to the next layer, until eventually the “output” layer is reached. The network’s “answer” comes from this final output layer.

One of the challenges of neural networks is understanding what exactly goes on at each layer. We know that after training, each layer progressively extracts higher and higher-level features of the image, until the final layer essentially makes a decision on what the image shows. For example, the first layer maybe looks for edges or corners. Intermediate layers interpret the basic features to look for overall shapes or components, like a door or a leaf. The final few layers assemble those into complete interpretations—these neurons activate in response to very complex things such as entire buildings or trees.

One way to visualize what goes on is to turn the network upside down and ask it to enhance an input image in such a way as to elicit a particular interpretation. Say you want to know what sort of image would result in “Banana.” Start with an image full of random noise, then gradually tweak the image towards what the neural net considers a banana (see related work in [1], [2], [3], [4]). By itself, that doesn’t work very well, but it does if we impose a prior constraint that the image should have similar statistics to natural images, such as neighboring pixels needing to be correlated.

Automatic Cinema aims at an artistic audience. The software can be used for exhibitions or installations, where a variety of media are served on various screens and channels – syncronized or not. Since all media assets are stored in a database, Automatic Cinema is also useful for documentarists and researchers with a structural approach to their material. And last but not least, Automatic Cinema is open source and can be developed by anybody. Instead of cutting a bunch of videoclips the hard way, Automatic Cinema generates countless versions based upon predefined styles. Probably, you'll end up seeing a movie you've never been thinking of — serendipity in it's best way.

Echo Nest Remix is the Internet Synthesizer. Make amazing things from music, automatically.

Turn any music or video into Python or JavaScript code.

Echo Nest Remix lets you remix, re-edit, and reimagine any piece of music and video, automatically and algorithmically.

Remix has done the following: played a song forever, walkenized and cowbellized hundreds of thousands of songs in a week, reversed basically everything, beat matched two songs, split apart DJ mixes by their individual tracks, made new kinds of video mashups, corrected sloppy drumming, synced video to a song, transitioned between multiple covers of the same song, made a cat play piano, and taught dogs to play dubstep. Check out all the examples here.

Remix is available as an open source SDK for you to use, for Mac, Linux, and Windows:

Install for Python: sudo pip install remix. Full installation details, packages for Mac and Windows, and complete Python documentation are here.

Try JavaScript: Test out remix.js here.

We describe a novel algorithm for extracting a resolution-independent vector representation from pixel art images, which enables magnifying the results by an arbitrary amount without image degradation. Our algorithm resolves pixel-scale features in the input and converts them into regions with smoothly varying shading that are crisply separated by piecewise-smooth contour curves. In the original image, pixels are represented on a square pixel lattice, where diagonal neighbors are only connected through a single point. This causes thin features to become visually disconnected under magnification by conventional means, and it causes connectedness and separation of diagonal neighbors to be ambiguous. The key to our algorithm is in resolving these ambiguities. This enables us to reshape the pixel cells so that neighboring pixels belonging to the same feature are connected through edges, thereby preserving the feature connectivity under magnification. We reduce pixel aliasing artifacts and improve smoothness by fitting spline curves to contours in the image and optimizing their control points.

SuperCollider is an environment and programming language for real time audio synthesis and algorithmic composition. It provides an interpreted object-oriented language which functions as a network client to a state of the art, realtime sound synthesis server.

SuperCollider was written by James McCartney over a period of many years, and is now an open source (GPL) project maintained and developed by various people. It is used by musicians, scientists, and artists working with sound. For some background, see SuperCollider described by Wikipedia.

PixiVisor is a revolutionary tool for audio-visual experiments. Simple and fun, cross-platform application with unlimited potential for creativity! It consists of two parts: Transmitter and Receiver. Transmitter converts the video (static 64x64 image or 10FPS animation) to sound, pixel by pixel (progressive scan). This lets you listen to the sound of your image. But the main function of the Transmitter is to transmit the signal to the receiving devices. Receiver converts the sound (from microphone or Line-in input) back to video. You can set the color palette for this video, and record it to animated GIF file.

pocode is an open-source C++ library designed by Potion for the production of interactive media across multiple platforms. pocode provides a robust, high-performance software infrastructure that allows for the creation of all types of software, from simple visual sketches to elegant mobile apps to entire software applications.

At the center of pocode’s design is a desire to make an all-purpose software library that is as simple to use as it is efficient and powerful. Thanks to pocode’s object-oriented architecture, applications stay organized and take care of themselves. Objects draw themselves, maintain their state and can be changed at any time. pocoders don’t have to worry about the intricacies of event routing, the details of threaded image loading or the pitfalls of shader construction. All of these processes are handled automatically.

At the same time, pocode is an open system that allows pocoders to dive deep into the software architecture and implement alternative methods of their own. Because of pocode’s modular design, this kind of tinkering and re-engineering can place without altering the library itself. pocoders can also extend pocode with their own poObjects, and share them with other pocoders. Since all poObjects fit within pocode’s object-oriented framework, shared poObjects can easily be incorporated into new applications, even across platforms.

While we have designed pocode with great intentionality, we see it as a work in progress. pocode is an evolving platform that will change over time in response to user feedback and to new technologies. Simply put, we want pocode to be the simplest, most useful and most technically sound software library available anywhere for the creation of interactive media.
