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.
And would it really be effective against bots? It isn't obvious to me why it would be any more effective than other schemes.
The irony of a new user who only posts about one topic saying this ...
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.
