Just by looking at this frame on your right, you would say there is no chance it depicts a perfect rectangle, right? But hang on there for a second! Let me show you what happens if we just remove the wavy frame surrounding the picture… Voila!
The inner picture now becomes a perfect rectangle! Be sure to check the #gif animation attached below for proof. It’s really strange how certain patterns can influence our perception of reality, do you agree?
This illusion was originally produced by Greeenpro2009, and you may see the video of it on Greeen’s youtube channel. I personally adore simple optical illusions (such as this one), specially when done professionally, and in such a visually appealing way. Goood job Greeenpro2009!
