Fair point on the naming collision. I know these sorts of color filters end up with different names via different apps on different platforms, so just describing it as 'redshift safe' seemed like the lesser evil.

And it's an great question about relativistic redshift! That actually would end up with more or less the opposite result: you'd want to shift all of your palette colors and meaning into commanded-blue channels.

That's because the relativistic redshift pulls everything to longer wavelengths, so as you approached the speed of light, you'd start literally losing colors as they got red-shifted out of the human visual range.

The first thing you'd lose is the red channels (which would get shifted into the infrared, and thus be invisible). That happens at about 0.2c, depending on the wavelength of the red LEDs in your screen.

Then you lose green once you get to about 0.38c.

Blue doesn't disappear from your visible range until you get up to ~0.52c.

Faster than that, and the only things you'll be able to see with naked eye started off as ultraviolet frequencies (or above)! (aka - you'd need HW changes to your screen, so it's outside the realm of SW to fix)

Added in a Table of Contents at the top to improve it for now. May do more substantial re-writes later.

Really glad you liked it! I use an absurd amount of redshift personally, and have spent too much time thinking about / working on light-and-color related projects, so it came out of a place of need and love alike.

Can I ask which parts? I wrote the intro section by hand, and left the rest of it Fable-generated with significant "guidance" and rounds of re-writing.

I think the current weakest part is the explanation of the science behind it, but I'm curious if there was anything specific that jumped out at you.

Example web pages is a great idea. It's a very new project (just did it over a couple of evenings during a trip last week), so there's nothing formal out there yet, but I'll add in some contrived examples later today.

It's interesting that there are essentially no pictures of the actual device anywhere on this page (except for a lone image, from the back of a user's head, where all you can see is the strap and the edge of the front).

Another ISSDC alum here, but from a little more than a decade earlier. It really was a unique experience. I remember the finals at Kennedy Space Center fully exercised the extent of your mental and physical stamina both. It also delivered lots of surprisingly applicable lessons for startup life around coordinating technical teams in high-stress, high-stakes environments.

1 AU is about 8.3 light minutes. So 6k AU is about 50k light minutes. with ~525k minutes in a year, that means that 6k AU/yr is almost exactly 0.1c.

I used to work on solar power plants and solar tracking technology back in the late 2000s. Even back then, I remember frequently discussing that "eventually panels will be cheap enough that we'll just wallpaper the world...". It's really nice to see that coming true.

Lordy, I clicked on this, fully expecting a discussion of a shape-pattern in the board game of Go, and somehow didn't have a thought in my mind for the real, completely different, meaning.

This reminds me of "trompe l'oeil foods"... dishes that appear to be one thing, but are another entirely. Or maybe optical illusions more generally.

I tried this once. There was no convincing effect for being able to "detect by feel" AC currents, but you could definitely notice magnetic materials.

Maybe the most fun, though, was just playing around and "picking up" paperclips and tiny screws by flicking my finger at them.
