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:

• Batch mode for changing GIFs in place.
• Prints detailed information about GIFs, including comments.
• Control over interlacing, comments, looping, transparency...
• Creates well-behaved GIFs: removes redundant colors, only uses local color tables if it absolutely has to (local color tables waste space and can cause viewing artifacts), etc.
• It can shrink colormaps and change images to use the Web-safe palette (or any colormap you choose).
• Optimize your animations! This stores only the changed portion of each frame, and can radically shrink your GIFs. You can also use transparency to make them even smaller. Gifsicle’s optimizer is pretty powerful, and usually reduces animations to within a couple bytes of the best commercial optimizers.
• Unoptimizing animations, which makes them easier to edit.
• A dumb name.

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.

Touché proposes a novel Swept Frequency Capacitive Sensing technique that can not only detect a touch event, but also recognize complex configurations of the human hands and body. Such contextual information significantly enhances touch interaction in a broad range of applications, from conventional touchscreens to unique contexts and materials. For example, in our explorations we add touch and gesture sensitivity to the human body and liquids. We demonstrate the rich capabilities of Touché with five example setups from different application domains and conduct experimental studies that show gesture classification accuracies of 99% are achievable with our technology.

The Social Collider reveals cross-connections between conversations on Twitter.

With the Internet's promise of instant and absolute connectedness, two things appear to be curiously underrepresented: both temporal and lateral perspective of our data-trails. Yet, the amount of data we are constantly producing provides a whole world of contexts, many of which can reveal astonishing relationships if only looked at through time.

This experiment explores these possibilities by starting with messages on the microblogging-platform Twitter. One can search for usernames or topics, which are tracked through time and visualized much like the way a particle collider draws pictures of subatomic matter. Posts that didn't resonate with anyone just connect to the next item in the stream. The ones that did, however, spin off and horizontally link to users or topics who relate to them, either directly or in terms of their content.

The Social Collider acts as a metaphorical instrument which can be used to make visible how memes get created and how they propagate. Ideally, it might catch the Zeitgeist at work.

#000000;">Imagine a kung fu flick in which the martial artists spout Situationist aphorisms about conquering alienation while decadent bureaucrats ply the ironies of a stalled revolution. This is what you’ll encounter in René Viénet’s’s outrageous refashioning of a Chinese fisticuff film. An influential Situationist, Viénet’s stripped the soundtrack from a run-of-the-mill Hong Kong export and lathered on his own devastating dialogue. . . . A brilliant, acerbic and riotous critique of the failure of socialism in which the martial artists counter ideological blows with theoretical thrusts from Debord, Reich and others. . . . Viénet’s’s target is also the mechanism of cinema and how it serves ideology.

Data portability is the ability for people to reuse their data across interoperable applications. The DataPortability Project works to advance this vision by identifying, contextualizing and promoting efforts in the space.

Pileus is an umbrella connected to the Internet to make walking in rainy days fun. Pileus has a large screen on the top surface, a built-in camera, a motion sensor, GPS, and a digital compass. The current prototype has two main functions: photo-sharing and 3D map navigation.

The photo function is connected to a major web service: Flickr API. A user can take photo with a camera on the umbrella, and pictures are uploaded to Flickr in two minutes with context tags via a wireless Internet connection. User can also enjoy theirselves watching photo-streams downloaded from Flickr with simple operation of wrist snapping.






It also has a function of 3D Map. Detecting a location data from GPS, it shows a 3D bird view around the user. User can walk-through a city comparing the 3D views and real sights, and the map is always updated by GPS and a digital compass. It aims to create natural augmented reality with a large informatin screen on the umbrella.



These two functions can be switched by simply fliping a switch. As a future direction of its development, putting a context data on the Internet (e.g. geo-tags on photos), it will be able to provide social local-navigations and real-time in-place communications. The product aims to provide an augmentation of everyday life synchronizing information on the Internet and the real place.

FRACT is a first person adventure game for Windows & Mac much in the vein of the Myst titles, but with an electro twist. Gameplay boils down to three core activities: Explore, Rebuild, Create. The player is let loose into an abstract world built on sound and structures inspired by electronic music.

It’s left to the player to explore the environment to find clues to resurrect and revive the long-forgotten machinery of this musical world, in order to unlock its’ inner workings.

Conservators at the Prado in Madrid recently made an astonishing discovery. They announced yesterday that the painting assumed to be a replica of the Mona Lisa, had actually been painted by one of his key pupils, working alongside the master. The picture is more than just a studio copy – it changed as Leonardo developed his original composition.

The so-called “Mona Lisa of the Prado” has long been in the museum’s collection, tucked away in its vaults and displayed only occasionally, its significance not fully understood. The experts thought it was painted by some Dutch artist because they assumed it was painted on oak (a wood not used by Florentine painters), but actually it was painted on walnut. In size, it is close to that of the original: the Louvre’s painting is 77cm x 53cm and the Prado’s copy 76cm x 57cm.

United Arab Emirates billionaire Sheikh Hamad Bin Hamdan Al Nahyan has etched his name in the sand on Al Futaysi island in Abu Dhabi in such big letters it can be seen from space.

A satellite image from space confirms the enormous letters of the name “HAMAD” carved into the sand on Al Futaisi Island in Abu Dhabi. The name stretches a staggering two miles long and will likely be a permanent fixture on the distant island.

The island of Futaisi lies near the barrier island of Bahrani, in a shallow sheltered lagoon-type complex to the southwest of Abu Dhabi Island.

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.
