It’s wild the algorithm isn’t promoting this video more. This channel is incredible. Please keep making videos, your channel will explode in popularity!!!!

Really cool display of illusions, I remember I had a book of illusions as a kid and always loved it

@username_not_found6926 3 месяца назад

I really liked the editing in this video. You managed to effectively point out key features of some illusions using only visual elements.

@codeinetcetera 6 месяцев назад

with the first illusion, i think it's also that the vertical line is on top of horizontal line, so it appears to our brain as though the width of the horizontal line contributes to the height of the vertical line

@ToyInsanity 5 месяцев назад

The vertical line is longer because it has a fraction of the horizontal line added to it.

@TunisianEnergy Месяц назад

thats because in this pic they are squares not lines, now take a thin pencil and draw the same thing, look away a minute then look back, you'll see the same illusion, his explanation is correct, our eyes is configured to see more horizontal then vertical because of the adaptation of what we see constantly on earth, everything goes more horizotal

I've experienced the motion aftereffect illusion after an extended period of time playing guitar hero - there are buttons moving towards you constantly on a moving fretboard and after a long time playing the game if you look away, e.g. at a wall or another part of the room, you see everything moving away from you.

I just discovered your channel and I am a huge fan now. It's rare that I find someone with such similar interests and tastes as I do (digging the Eyeliner in the background by the way). Keep it up man 😁

@dpi3 3 месяца назад

such a fun video! the comprehensive analysis of the illusions were great

@Laura-kl7vi 5 месяцев назад

I just discovered your content and it's great. I love your deep dives, thoughtfulness, and even your voice.Your videos are both enjoyable/entertaining and also make me think. So I subscribed. I saw you don't make videos often and it's my (selfish) hope you'll be able to them more frequently. Thanks for what you do.

You should also talk about the optic nerve blind spot! Also, this is super interesting for me. I am almost completely blind in my left eye so my vision is 2D. None of the 3D illusions work for me at all

@David.C.Velasquez 6 месяцев назад

Your brain's visual processing centers, actively hide the 'blind spot' from your consciousness. Can you imagine if this wasn't the case? You would be aware of a 'hole' in your visual field, that would likely breaking any illusion of immersion.

@nfrcomputers 6 месяцев назад

@@David.C.Velasquez yes, but look up optic nerve blind spot and read the wiki article. you can prove that it is a real phenomenon by the test on wikipedia or on another website. you close one eye and look at a dot in the center and a off-set dot. at a certain specific eye distance the off-set dot seems to dissapear into the background when the eye is focused on the center dot.

@sonicwaveinfinitymiddwelle8555 3 месяца назад

1:55 when i first saw this thing I immediately thought of combining the arrows to make X on both sides therefore answering the illusion

@clint4527 6 месяцев назад

I really like the different domains you use to make sens of this. Please, make a follow up with pattern, you got really cool stuff with conway, pentrose and a relatively recent breakthrough by a random to a problem that keep math ppl up for a very long time.

This dude makes higher quality videos than most bigger channels

@s0urp0wer5 3 месяца назад

I am not sure why but the impossible looping objects like the infinite stream leading to a waterfall make me SOOO queazy more than other optical illusions. Their mind breaking existence is likely whats doing it. Lovecraftian. Great video.

Dude, RU-vid didnt recommend this video to me, and youre one of my favourite channels. I had to come here myself to check if there is any new video. The low views are not the video fault.

14:50 this was created in real life. It's an installation in a little walking path along a little river in Freiburg or Straussburg. There are three bars, the left goes diagonal pointing up and away from the viwer, one longer horizontal, the right also diagonal pointing up and towards the viewer \_/ some 20 or 30 feet away , a couple feet off of the ground was a plate with a small hole. Crouched and looking there only there, you see the impossible triangle. I'm sure others have done it, but thank you for talking me back to that

If you measure all the foods you eat with a gram scale and MyFitnessPal, and estimate your caloric output with a tracker and/or scale, you don't need to worry about whether or not you're over serving or under serving.

@cheshire1 6 месяцев назад

Our interpretation of Sander's Parallelogram isn't even a mistake. It's just our brain interpreting what we see in 3D, which is exactly what it's supposed to do.

I have had only one functional eye since 2020. The two line vertical horizontal illusion worked on me.

@bigjoe4695 Месяц назад

it really screwed with my head when you showed the waterfall and then the grass image just contorting.

@Siuolplex 5 месяцев назад

I explained 3:38 to myself as being a result of our minds accounting the full shape being larger or smaller when looking at individual lines I guess I was (Kinda) wrong though haha

Creepy how the banner ad at the very beginning was... in Finnish? Of all the languages, it's my native one for some reason 🤷‍♂

@etunimenisukunimeni1302 6 месяцев назад

For a second I honestly thought that was the point, that it was the illusion - "no matter who you are, you'll see this ad in your language", resulting in a momentary brain explosion 😅

I hate it when you put hundreds of hours into a project. Just for the algorithm to say. " your video isn't worthy of viewers right now" then they promote a Skibidi Toilet video instead. SMH
