Dancing drones in the night sky
The Ars Electronica Future Lab has been attaching LED’s to small drones and sending them up in the sky to produce intriguing light shows that are causing quite a stir on the ground below. Some people even swear they’re watching flying saucers.

Visualia 2014 in Pula: Interview with organiser Marko Bolkovic (Includes first-hand account).
You dont have to be a large City to be innovative and creative…..Pula in Croatia has only approximately 55,000 people.
“In ancient times, Julius Caesar painted his fleet of reconnaissance boats entirely in a blue-green wax — including the sails, ropes and even the crew — making the vessels virtually invisible against the sea. In a sense, camouflage is the original invisibility cloak, one that animals have evolved to such stunning perfection that they can disappear before our very eyes. It’s a marvelous trick for survival.
But beyond hiding from the view of hungry predators or opposing soldiers, the idea of invisibility has long captured our imagination, notably the imagination of “Harry Potter” fans and random physics geniuses who strive to create real-life invisibility cloaks. One such brainiac, Baile Zhang, an assistant professor of physics at Nanyang Technological University in Singapore, showed off his “invisibility cloak” on Monday at the TED2013 talks in Long Beach, Calif.
Presenting as part of TED Fellows Day, a day when young researchers, artists, and other assorted brilliant minds are selected to give four-minute talks, Zhang awed the audience with his awesome cloak.
Zhang’s device is in its early stages; just a small gizmo in prototype phase — but it works. Speaking to Carla Sinclair of Boing Boing, Zhang explained that the cloak is made out of two pieces of natural calcite (optical crystals) that are joined together. The calcite bends light and suppresses shadows, tricking the eye into seeing nothing.
Sinclair writes of the demo, “The cloak’s ability to conceal an object so that both the cloak and the object become invisible was astonishing. Zhang placed the cloak over a bright pink Post-it note and voila! Nothing! The pink paper disappeared. And the cloak itself wasn’t really visible in the first place.”
As inventors generally have a purpose in mind for the innovations they conjure up, it’s logical to assume that Zhang’s extreme camouflage machine is being developed for the military or some other high-end application, but no. When asked what his plans were, he said that it had no purpose, he “just created it for fun.” Such are the hobbies of whiz-kid wizards.
AN : writers have written, concocted the thoughts and ability of invisibility from comic book characters to science fiction. It is not altogether beyong capability, as this TED Talk participant demonstrates. If one thinks about it, the visible spectrum of light is what we operate in….yet the electromagnetic spectrum is much broader than just our visible light receptor spectrum . Think , for example, infrared spectrum. We cannot see that spectrum but with instrumentation, we can “see” in the IR range. It should not surprise that we then can de-visualize. The applications of this are intriguing.

“Artist and light sculpture pioneer Makoto Tojiki is one of the most brilliant sculptures in modern day. He mainly works with light, and what fits better in a futuristic home than a couple of innovative light sculptures, right? His artwork, called No Shadow, has become a viral sensation and can only be described as a cord carbon copy of the holographic system. Standing at a distance will make it appear as such, and even if you walk up to it to take a closer look, you will be amazed by the accuracy that Makoto managed to implement into his sculptures with just a few lights.”
