A mind-bending optical illusion involving a '3D cube', which literally makes you think outside the box is going viral on social media.
The video, taken from YouTube channel ¡®Sonhos com Dimens?o¡¯, was shared by Science girl on Twitter. In it,?an individual can be seen drawing several distorted lines on grid paper before folding the sheet in the middle so the top half stands upright.
At first, if you look from several angles,?it might not look like much. However, if viewed from the right position, the lines merge to give the impression that a square is jumping off the page.??
¡°Keep one eye closed and see the magic,¡± the video reads.
Thankfully,?Science girl?explained what was taking place, writing that the shape is ¡°adjusted by your point of view¡±.
¡°This type of illusion where a distorted drawing appears normal when viewed from a particular point is called anamorphosis,¡± they said.??
That might look simple, but it sure is tricky.?
Recently, another optical illusion, showing a?stack of cubes?went viral.?
In a video shared on?YouTube, a?cube art is placed on a flat surface - but can you work it out?
Michael Cheshire, who built the art,?explained all about the?illusion, which is a two-dimensional work made from wood veneers on a solid background.
In the description, he said: ¡°The impression of depth is caused by the choice of three colours of wood arranged in a hexagon to look like a 3D cube.?With many hexagons arranged to overlap and of differing sizes the 3D effect becomes magnified. Adding the larger outer hexagons makes another illusory cube which encloses and balances the whole design."
¡°The gaps between also help to give the structure a 3D effect overall. Even when shown that it is flat, we are compelled to see it as 3D," it added.?
The perplexing illusion was shared as part of the best illusion of the year contest which celebrates the most mind-blowing images from around the world.? ??
Another illusion, which challenges the viewers to spot a bear hidden in plain sight, also went viral recently.
The old artwork shows a hunter, bent on his knees and gun in hand, creating an impression that he is looking for a target in a snow-covered forest.??
The drawing, shared by?Playbuzz, may seem to trick you into believing there's no bear, But there actually is a large?grizzly bear?somewhere in the background.?
Well, look closely and you will find the bear disguised as a cliff face in the background.
