What if Hacker News had a optical illusion captcha?

By asking visitors to correctly say which direction of say, four (up, down, left or right) a part of a captcha appears to be "moving", it filters out the bots while allowing humans with optical illusion fooled eyeballs to pass the test. Given 16 of those captcha requests in a row and given that there are 2^2 choices per captcha, there is a 2^16*2 - 1 possible ways to enter 16 captchas wrong, but only 1 way to enter them right, leading to a filtration failure of around 1 in 4 billion.

Also, multiple captchas can be done in a row for each failure, but once say, 16 captchas have been solved in a row, access is granted for say, a month, until the captcha has to be done again.

It just feels like Hacker News is full of bots and I have a solution to this.

It seems like this would bring all of the problems of other CAPTCHAs, but with the additional problems of excluding the visually impaired as well as those who can't see optical illusions (which is as high as 20% of the population, depending on the specific illusion).

And would it really be effective against bots? It isn't obvious to me why it would be any more effective than other schemes.

How will visually impaired users leveraging screen readers complete this? How will individuals who have a form of motion sickness complete this?

Simple, they can ask someone for help.

"You have to go ask someone for help to participate." seems like a cruel policy.

Well, they have the advantage of people wanting to take care of them.

I can't tell if your response is ignorant or uninformed. Please enlighten me.

The irony of a new user who only posts about one topic saying this ...

I have two other accounts that don't just have me discussing one topic: https://news.ycombinator.com/user?id=vitalmixofntrnt and https://news.ycombinator.com/user?id=pantantrant

Edit: I asked a mod to merge those two accounts into this one.

I just like the word vita more now than vital and I'm big on the Vita branding that I want my startup to have its products and / or services to have, like say, in the future, Vita Shampoo, Vita Detergent, etc.

Also it feels like the whole internet is like that, "Dead Internet Theory" and all that, but instead of just whining, I have a solution.

(We've merged all these accounts now, by the owner's request. I just mention this in case people click on those links and are puzzled.)
