Lucky Knot The Lucky Knotbridge is a topologically fascinating structure. The bright red truss bridge, which spans the Dragon King Harbor River in Changsha, China, twists and knots like a tangled shoestring. Its steely, 600-foot spine swoops into an infinite loop, with no clear end point. #fun @WhatDoYouSea

Dichroic prism A dichroic prism divides light into red, green, and blue, to form three pictures that utilize these corresponding colors from the LCD (HTPS) panels. Color and image are recomposed by reflecting red and blue light and transmitting green light. The prism is formed by combining four triangular poles to create one rectangular solid. High precision is required in the processing and adhesion of poles to avoid dark lines and double images caused by misaligned dichroic surfaces. #classic @WhatDoYouSea

Sculpture Illusion Is it posssible to view an object from different positions? We say yes! #classic @WhatDoYouSea

What Is Illusion Art? Illusion art is the depiction of an object on a flat, two-dimensional surface. The rendering of the object, still life, or scene is in a three-dimensional manner, which makes it appear real to the viewer. #classic @WhatDoYouSea

Uyuni Salt Flat Salar de Uyuni is the largest salt flat in the world and one of the most amazing natural attractions of Bolivia. Whether you're walking on the seemingly endless white, desolate surface of the dry flats, or admiring the simply perfect reflection of the clouds and blue sky above when there's water — all travellers agree the Salar de Uyuni offers an out-of-this-world experience. he flats cover an area of over 10,000 km² and to see the best parts, you'll need to cover quite some ground. While it's possible to explore this unique piece of land on your own, most visitors opt for organized tours along some of the best sights. #fun @WhatDoYouSea

Optical illusion and how it works Seeing is believing, right? Well, actually… What you see and what you think you see are different things. Your senses gather information and send it to your brain. But your brain does not simply receive this information—it creates your perception of the world. This means that sometimes your brain fills in gaps when there is incomplete information, or creates an image that isn’t even there! Why does this happen? Evolution! Survival depends on fast reactions. Your brain has evolved to work quickly to piece together whatever bits and fragments it can get - and to do its best to figure out the rest. #classic @WhatDoYouSea

The Bund Finance Center The Bund Finance Centre – a major new mixed-use development jointly designed by Foster + Partners and Heatherwick Studio – is set to revitalise Shanghai’s waterfront. Occupying a prominent site on the Bund, the buildings define the 'end point' to Shanghai's most famous street. The 420,000- square metre masterplan is highly permeable for pedestrians, with the design conceived as a point of connection between the old town and the new financial district. Inspired by this urban context, two 180-metre landmark towers are placed in the south of the site, while the buildings facing the waterfront are staggered in height and relate in scale and rhythm to the grand nineteenth-century landmarks along the Bund. At the heart of the scheme is a flexible arts and cultural centre, home to the Fosun Foundation, which combines exhibition and events halls with a performance venue, inspired by the open stages of traditional Chinese theatres. #fun @WhatDoYouSea

Evolution Tower, a distinctively luminous landmark on the Moscow night skyline Evolution Tower, the skyscraper designed by Tony Kettel and Karen Forbes, became a landmark in Moscow’s new urban skyscape throughout it's construction between 2011 and 2014, the year in which it was completed. Since 2016, when it was bought by Transneft, the building has been the headquarters of the largest state-owned oil pipeline company in the world. The tower is 255 metres and 55 floors high and is now the largest and most efficient office building in Russia. It is lit entirely by LEDs and boasts one of the most sophisticated management and control systems on the planet. #fun @WhatDoYouSea

Shepard Tone Listen to the sequence of tones. Maybe adjust volume. The tone rises in pitch from step to step – and continues to do so, endlessly. Really? That’s impossible… Roger Shepard invented this acoustic illusion in 1964. His basic idea was as follows: When the pitch rises one step, the harmonic composition is altered (a little less high, a little more low harmonics). This is done in such a way that after 11 steps the harmonic content corresponds nearly to a tone one octave lower. With the next step the sequence resorts to the first one. #classic @WhatDoYouSea

The Rubber Hand Illusion The Rubber Hand Illusion (RHI) is a tantalizing illusion, where the feeling that a rubber hand belongs to one's body (feeling of ownership) is brought about by stroking a visible rubber hand synchronously to the participant's own occluded hand. In the first work describing this phenomenon, Botvinick and Cohen [1] showed that two types of measures are affected. Participants rated the subjective experience to own the rubber hand high in a questionnaire if stroking was synchronous but not if stroking was asynchronous. In a second experiment, perceived position of the participant's left index finger was measured by an inter-manual reaching task in darkness. A displacement of reaches towards the rubber hand occurred in the case of synchronous stimulation, but not in the case of asynchronous stimulation. This displacement effect has been referred to as proprioceptive drift. #classic @WhatDoYouSea

Face on Mars In 1976 the Viking Orbiter radioed back many images from Mars. Among those form the Cydonia region, one depicted a rock formation that strongly resembled a human or humanoid face staring straight up into the heavens. You can probably guess what was made of this… ‘Pareidolia’ is the term for neurological or psychological phenomena where vague images are interpreted by the brain as specific images. Statistically speaking, it is a type I error, a “false positive”. FYI: the second image is 100% the same area on the Mars, however under a different angle. Not so human anymore, huh? #classic @WhatDoYouSea

The Delboeuf Illusion (cont'd) Remember the previous post about the circles? Well today is a real life hack. In a cafeteria, choose a smaller plate! You'll feel more full in a shorter time, because your brain will tell you that you ate more, than you actually did. And if you are the cafeteria owner, you know what to do, don't you? ;) #classic @WhatDoYouSea
