Optical illusions of the year

Have a look at some of these, optical illusions always fascinate, I’ve never seen one that rotates in both directions around horizontal and vertical axes before.

Very cool.

On the second one, I got yellow dots going left to right, but couldn't see red and green dots going from top to bottom.

Why is this?

Put on your headlight and sound your horn if people get in the way. (Innes)

I'm blind as a very short sighted bat. With my glasses on and phone a couple of feet away I could only see yellow. Glasses off and a few cm away I could oly see red and green

The Chunder Thunder Illusion (direct link) is brilliant.
Warning - it might be seizure inducing...

I'm also as blind as a Dienst. Maybe I would have the same results. I haven't tried yet.

I can make it work as advertised on my proper computer screen, if I kind of blur my vision (even more) as I try to make it switch. I wonder if that one has its tiny dots interacting with the different screens in some way.

I like the one where the dot is going round, bamboozled by the circles going round that.

If you look at the sides then you can switch to seeing lines going down, if you look at top or bottom you can switch to seeing lines going left-right.

The Ames' Window Illusion, 50 years old this year, remains one of the very best. Look what goes on later, around 3m and 4m, when he sticks a match box to it, and then fixes a ruler through the window. It becomes quite mindboggling. Even though the guy has already shown you it is just a flat piece of cardboard, with a vertical pin so you can make it rotate around a vertical axis on a turntable, you just can't make yourself see the reality of what is happening. At least, I can't.
