I made another variant on the illusion idea some time ago. It is drawn a little messy, but here you go. It looks like it has spirals, but there are none. -
Ann K replied to the thread Reducing Contrails.I recall the day after the Twin Towers went down, the sky was incredibly blue, unprecedented in my urban area, because all the planes were grounded. It sounds like a good idea, but has Gates have anything more than ('scuse the expression) "pie in...

Ann K replied to the thread Optical illusions.Refer to @Ravi 's illustration, post #3 again. The white diamonds have a black line and the black diamonds have a white line in exactly the same position, but the top row of lines slants downward while the others slope upward.

Thank you. My instinct is "but they ARE sloping towards each other!!!" (as in individual pieces), then I see the whole and I'm "ohhhhhhhhhhhhhhh". I like how you can almost see the effect passing through as you concentrate on more and more...

The top two rows seem slanted toward each other, but they're not.

The perspective does work, and that's the reason for the illusion. In vanishing point perspective, any set of parallel lines converges on the same point on the horizon; conversely, any set of lines that converge on a point on the horizon are...

Like.
I have made a lot of analysis and datasets concerning the VASCO 2024 sample (107K rows) and related source materials during this year. I will publish the relevant ones as reports, code etc. at some point. I want to continue analyzing other... -

Agree.
Incredibly frustrating and disappointing. Excellent work as usual by you. Some of the best I've seen on this entire site -
About a decade ago I wrote a KSP (Kerbal Space Program) themed version of "2001: A Space Odyssey", played for laughs. I followed up with a little, documentary style story, about the work of the director on the movie, "Stanley Kerman" (a rip on...

Can be done with a simple strangefeelingometer.

Not really. AARO delivered work product, and Sean Kirkpatrick was very open about how AARO works, and what it can access. I don't know Kirkpatrick or anyone else who works for AARO, but I can see how they go about what they're doing, and I trust...

Not piling on, but just expanding on what @Mendel talked about above. It's not just that ARRO said this and UAPTF said that. It's looking at how they worked and who was involved. The UAPTF was a bit of an ad-hoc throw together after the NYT... -
Ah, yes. I drew a similar illusion a while ago:
