From the GPS that give us directions to the drones that drop bombs, the digital shapes our culture at every level. So why is digital art still a sideshow? As a groundbreaking new exhibition opens, James Bridle looks at pioneering works from the first arcade games to films made fully in CGI – and argues that it's high time we took it seriously
An interactive documentary intended as a “living report” that will be continuously updated, Shout Art Loud shows how Cairo residents are using different tactics to fight rising sexual harassment, including pro-women graffiti, drama workshops and street performances.

Today, thanks to computer graphics and digital drawing tablets, we see tons of artwork that has been made with the help of a computer. Computers and art have long gone hand-in-hand, and here you can see some of the earliest pieces of computer-assisted art.
Creative photos you never seen before. There are hundreds of creative photos & photo manipulation artwork publish on deviantart, flickr and other networks every day. However when it comes to finding the right photo; one can easily spend hours...
This month sees the dawn of fresh names in the virtual art world, with Lagu Indigo and Stardove Spirit taking the lead for the August round of the 4th cycle of the LEA Full SIM Art series at LEA 6. A full list of the LEA Full SIM offering since inception in 2011 can be found HERE. Anyone interested in applying for either Dec 2014 or Jan 2015, please contact Jayjay Zifanwe with your interest and preferred month.
As a quantum state collapses from a quantum superposition to a classical state or a different superposition, it will follow a path known as a quantum trajectory.
In a recent paper in Nature, scientists from the University of Rochester, University of California at Berkeley and Washington University in St. Louis have shown that it is possible to track these quantum trajectories and compare them to a recently developed theory for predicting the most likely path a system will take between two states.
Andrew N. Jordan, professor of physics at the University of Rochester and one of the authors of the paper, and his group had developed this new theory in an earlier paper. The results published this week show good agreement between theory and experiment.
For their experiment, the Berkeley and Washington University teams devised a superconducting qubit with exceptional coherence properties, permitting it to remain in a quantum superposition during the continuous monitoring. The experiment actually exploited the fact that any measurement will perturb a quantum system. This means that the optimal path will come about as a result of the continuous measurement and how the system is being driven from one quantum state to another.
Kater Murch, co-author and assistant professor at Washington University in St. Louis, explained that a key part of the experiment was being able to measure each of these trajectories while the system was changing, something that had not been possible until now.
Jordan compares the experiment to watching butterflies make their way one by one from a cage to nearby trees. "Each butterfly's path is like a single run of the experiment," said Jordan. "They are all starting from the same cage, the initial state, and ending in one of the trees, each being a different end state." By watching the quantum equivalent of a million butterflies make the journey from cage to tree, the researchers were in effect able to predict the most likely path a butterfly took by observing which tree it landed on (known as post-selection in quantum physics measurements), despite the presence of a wind, or any disturbance that affects how it flies, which is similar to the effect measuring has on the system.
"The experiment demonstrates that for any choice of final quantum state, the most likely or 'optimal path' connecting them in a given time can be found and predicted," said Jordan. "This verifies the theory and opens the way for active quantum control techniques." He explained that only if you know the most likely path is it possible to set up the system to be in the desired state at a specific time.
