Petros Vrellis has created an interactive visualisation and synthesizer that animates Vincent Van Goghs “Starry Night”, using openframeworks to create a simple and elegant interaction. A fluid simulation gently creates a flowing fabric from Van Goghs impressionist portrait of the Milky Way and night sky over Saint-Rémy in France using the thick paint daubs as the particles within the fluid.
A touch interface allows a viewer to deform the image, altering both the flow of the particles and the synthesized sound, and then watch it slowly return to its original state. The sound itself is created using a MIDI interface to create a soft ambient tone out of the movement of the fluid that underscores the soft movement. Beauty through simplicity at its finest and most playful.
- About 80.000 particles move around with a fluid-like algorithm and are drawn as small opengl minimaps.
- The velocity field was not computed automatically, I had to set it manually myself. It was quite difficult to get it right…
- I get about 30fps at 1920×1080, with an intel i5-2500K, and a geforce GTX560.
- Multitouch tracking is made with ofxKinect and ofxOpenCV.
- The music is the result of much experimentation and luck.
UPDATE 30/03/2012: iPad 2 Version now available in the AppStore.

- Trace Modeler [openFrameworks] Created by Karl D.D. Willis, Trace Modeler is an application that uses real-time video to create three-dimensional geometry. The silhouette of a foreground object in a video frame is subtracted from the background and used as a two-dimensional slice. At user-defined intervals new slices are captured and displaced along the depth axis. The result is a three-dimensional model defined by silhouette slices over time. Trace Modeler was built using the openFrameworks and the OpenCV library to recognize contours from the video image. Source code is available for download here.

- Kometen [iPhone, Games] A comet has been born, please take good care of it! Explore the universe and learn how to fly in a graceful way and explore space to find art is what you need to do in the latest game by Erik Svedäng with Niklas Åkerblad. The art (which is all watercolor - see video below) takes you on a visual journey painted by Niklas. There are no points to win or loose in the game. Erik and Niklas have created a colourful universe for exploration where the skillful control of your comet is your prize. You swipe your finger to fly away from a planet you are orbiting, eating will increase the boost which helps you travel faster and when the boost meter is full you can do a long swipe to activate the super boost flying you a much long distance. There are 14 planets to uncover, each one a beautiful drawing. ‣ Super minimalistic controls: tap planets to gravitate towards them, swipe to let go ‣ Zoom through space at incredible speed! ‣ Explore a world filled with gorgeous watercolor art ‣ Hypnotizing and awesome soundtrack (which can also be heard in the trailer) The game was created using Cocos 2D, a framework for building 2D games. About the creators: Erik Svedäng (design & programming) is the creator of the PC game Blueberry Garden, winner of the Independent Games Festival Grand Prize 2009. Niklas Åkerblad (art, animation, sound & music) is the art-director of Colosseum for XBOX indie games. Platform: iPhone Version: 1.0 Cost: $2.99 Developer: Erik […]

- Action Painting Redux [openFrameworks] The spectacle and surplus masculinity of Hollywood is hardly run-of-the-mill source material for generative art, but Canadian software artist Jeremy Rotsztain has been diligently exploring transforming cinematic convention into rich, abstract compositions for three years now. Rotsztain's Action Painting project (first featured on CAN in fall 2009) employs scenes and sound design—'data' from action movies—as raw material to generate abstract expressionist style animations. "Revving Motors, Spinning Wheels" (below) is one of four videos released by Rotsztain this summer that illustrate just how far this project has come – the piece reads as a love letter to both Jackson Pollock and Jason Bourne. On close viewing the source material (culled from Ronin, The French Connection, etc.) is clearly organized thematically and the video functions as a serial examination of the stock components of definitive chase scenes. Screeching brakes, blaring sirens, lead-footed acceleration and the inevitable Ballardian-endgame all filter through the mix in clusters of topical clips. Jeremy provided the following contextualization (and above screen capture) of his working process on this piece over email: "...the software I wrote for arranging/orchestrating the clips has the same multilayer functionality of After Effects — but with the ability to select clips algorithmically from a database. You can ask for 45 seconds of clips featuring revving engine sounds then organize them by movie source and specify how much of the screen should be filled. This is basically what you're hearing/seeing around the one minute mark of "Revving Motors, Spinning Wheels" – and the sounds stand out because they're grouped together using similar 'gestures': cars flying across the screen, cars turning, police sirens and revving engines. There's a minute immediately following that where the clips are more randomized but with more intense moments from different movies (which uses a 'sort by intensity' functionality)." Jeremy has essentially built his own sequencer/mixer workflow for organizing and processing tagged clips – other videos in the series consider the sound and fury of brawls, explosions and gunfights. Rotsztain was recently the subject of a detailed interview with Dylan Schenker for The Creators Project where he elaborated on the nuanced relationship between his process and painting: "...it’s become more enjoyable to use the data in a more expressive fashion—to go beyond the informative practices of data visualization—and I decided to abstract the data and turned to audio/visual composition as a model for how the work should be experienced. So the end result is an artwork that looks like painting, but feels (and is edited) very much like cinema. Actually, when exhibited, the videos are are projected in high definition onto canvases, echoing both the immersive experience of abstract expressionist painting (where you stand in front of a canvas and let it envelop you) and the intense spectacle of action films."

- Dr. Mandala [iPhone] Currently in review Now available is the new iPhone painting application by Kenichi Hamada that allows you to create mysterious swirling patterns from dots on a revolving canvas. Inspired somewhat by the 60s spin art and work of Alfons Schilling and even later our own Damien Hirst, Dr. Mandala is a digital version of very popular rotating canvas painting. Included also is a high level of customisation of how your dots appear and behave on the canvas. Besides being able to changed the dot size, you can also change the dot shape (only 2 available for now). You can turn the grid on/off to guide the dots or load an image from your photo album to paint over. There is also a bunch of shake operations as you can see in the video but I have never been fond of having to shake the phone to do anything so this one is on you. Dr. Mandala, as appears in the video, does produce some pretty incredible patterns. I do like that the author adds a message to warn that: Staring for prolonged periods at rapidly rotating pictures may cause nausea. If this happens, please stop using this application immediately. Sounds like a must =] Dr. Mandala (thanks Kenichi) Platform: iPhone Version: 1.0 Cost: Free to try + $1.99 upgrade to full version Developer: Kenichi […]
- PlayART for iPad – Uniting classic art and children’s creativity Created by Tapook, PlayART is an iPad app aimed at children aiming to unite the worlds of classic art and children's creativity. Designed for children aged 5-13, but suitable for parents too, you can play with objects and shapes taken from these artists' original paintings, move, rotate and resize them however they like to make new creations, including combining elements from several or all of the painters. Five painters are included: Van Gogh, Klee, Rousseau, Monet and Cézanne. We think it's about time children were given the chance to mash up classic artworks and create their own paintings with Van Gogh's sunflowers, Monet's waterlilies and Cézanne's fruit. This way, they learn while playing and exercise their creativity. The team is currently working on the next release of the app which will feature five new artist and interactive features.
