Chaotica is a next-generation fractal art application, designed for both novices and professional artists.
Novice users can enjoy editing randomised fractals to produce stunning HD wallpapers and animations.
Professional users will particularly value the fast, modern rendering engine. High quality animations and huge images for print are easily produced, with real-time imaging controls that will dramatically accelerate your workflow.
What is fractal art?
Fractal art is a digital art medium with a very rich creative space, based on geometry and recursion.
Chaotica's user interface abstracts much of the maths away to provide a fluid artistic process.
Since its invention in 1981, IFS fractals have been popularised by Flam3 and Apophysis. Chaotica extends the creative possibilities of these programs in a powerful, production-oriented environment.

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.
Playscii is an open source ASCII art program, the successor to EDSCII. It runs on Windows and Linux, and will run on Mac OSX soon after a bit more work.

Please note that Playscii is open source, still in early development, and is offered as a pay-what-you-want download here on itch. Testing and bug reports are appreciated!
Fragmentarium is an open source, cross-platform IDE for exploring pixel based graphics on the GPU. It is inspired by Adobe's Pixel Bender, but uses GLSL, and is created specifically with fractals and generative systems in mind.
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.
Gifsicle is a command-line tool for creating, editing, and getting information about GIF images and animations. Making a GIF animation with gifsicle is easy:
gifsicle --delay=10 --loop *.gif > anim.gif
Extracting framesfrom animations is easy too:
gifsicle anim.gif '#0' > firstframe.gif
You can also editanimations by replacing, deleting, or inserting frames:
gifsicle -b anim.gif --replace '#0' new.gif
Some more gifsicle features:
Two other programs are included with gifsicle: gifview is a lightweight animated-GIF viewer which can show animations as slideshows or in real time, and gifdiff compares two GIFs for identical visual appearance.

Context Free is a program that generates images from written instructions called a grammar. The program follows the instructions in a few seconds to create images that can contain millions of shapes.
Electronic motion seems often artificial, synthetic... well... in fact it does not convey any emotions. By defining new rules to create movements, eMotion is a new kind of software made for visual live animations. As it is based on real world physics law,
