I think the live map is cool but (1) I don't know where to get that data and (2) seeing things at 100x speed is, IMO, more interesting as a visual
It's based off schedules but only Toei's schedules are easy to get (AFAICT). I got permission for the most of the others, but I thought the visual was good as is ... mostly. Maube I'll revisit.
Same with the Camera App. It can ask "Camera App wants to access your Camera" and you can say "No" and then download some other camera app and make that your default and grant it camera permission.

Browsers (and machines) were slower then so it didn't finish as fast as it does today. Also, it's hard to decide what steps to illustrate/count. Is a swap 1 step (swap) or 4 (load slot N to R1, load slot M to R2, store R1 in M, store R2 in N) etc...
A worked on a 3d asset generator with nodes (like Blender/Houdini)

I worked on a couple of design generators

It was just an experiment and I probably won't work on it more but still, I was blown away with how far we got. There's a quite a bit we worked through even though it was only part time of those 4 weeks.
It was used extensively in outdoor games like Jak and Daxter.
Browsers generally only allow a fixed number of WebGL contexts per page. So a generic element effect library has the issue that too many elements some will start losing contexts. The workaround is to just make one large screen size canvas and then figure out where the elements are you need to draw an effect for. now you only have one context drawing all the elements. But, you can’t know where to draw until the browser scrolls and renders so you’re always one frame behind.

WebGPU doesn’t have this issue. You can use the same device with multiple canvases

I went to gemini, picked "cavnas". used this prompt
> There's a famous CG scene in the movie Hackers where they "Hack the Gibson". It shows a bunch of translucnt cubes with glowing edges. The textures on the cubes are live computer text. The camera slowly flyies between the cubes tilting gracfully and it searches for the main one.
> Reproduce this scene in Javascript. Be sure to include each of those features
> 1. live computer text which you can simulate by drawing to a canvas offscreen and uploading to a texture, adding more output as it goes. You can even use "function.toString()" of the code you write as input
> 2. a post processing step so we get a glow
> You can probably use three.js for this
Here's the result.

No, it's not as good as the site linked above and it's unlikely it would be. On other hand, it got this far on the first try. Maybe a few more iterations and it could get the stuff you want.
Non-ascii, I tried various subsets of Unicode. There’s the geometric shape area, CJK, dingbats, lots of others
Different fonts - there are lots of different monospace fonts. I even tried non-monospaced fonts tho still drawn in grid
ANSI color style https://16colo.rs/
My results weren’t nearly as good as the ones in this article but just suggesting more ways of exploration

Note: options are buried in the menu. Best to pick a scene other than the default
Most of the music I like is loops pasted together in some DAW. Sure, it requires taste to make a good song but if AI figure out how to replicate that taste can crank out catchy tunes I wouldn't have a problem with it. I can only guess though that too much of a good thing will lead to be getting bored with it ... maybe.
It's not like most pop music isn't formulaic. I enjoy the currently popular songs from K-Pop Demon Hunters but they're so cliche, if they turned out to be AI generated I wouldn't be surprised :P
Like a simple example, I expect if have a object selected and press Cmd/Ctrl-C, Cmd/Ctrl-V I get a duplicate.
These interactions seem like basic table stakes

If you click save you get the option to use a URL.
The problem with a URL every edit is a new URL. So you send the URL to a friend, then fix a typo, they need a new URL.
The other problem is of course the space limit.
There are ~40 million in the PST time-zone. Some percent have smartphones (80%+), ~50% of those are iPhones (16 million). Of those, the majority are set it English (80%+), and are divided into screen sizes. But basically, if you have an iPhone, you have the same fingerprint has at least a million other other people in the PST time size. You are at best, 1 of 100, not 1 of x,xxx,xxx,xxx.
You might be x,xxx,xxx,xxx of people who visited that unpopular site but no one needs tracking on an unpopular site. On a popular site you will not have a unique finger print.
But, they are bucketed

It's not zero pieces of info but it's also not close to as bad as it looks. Effectively, everyone who has, say an NVidia GPU, will likely have the same list of features and limits.
As a more general example: The number is just a flat out wrong
> Unique to 1 in 2,147,483,648+ devices.
No, I have an iPhone Pro and am in the PST time zone, set to English. It has the exact same finger print as millions of other devices among the 40 million people in the PST time zone. In general, The only things different between 2 iPhones of the same model are time-zone, laguange setting, and font size.
Please STOP EXAGGERATING!
I tried this in 2014 with happyfuntimes

My conclusion was, past a certain number of people no one wants to game
Around the same time was AirConsole and still available
Nintendo also claimed a patent on showing a ghost image of your previous race (the ghost car in Mario Kart)
Things you can't do traveling long term.
● for many it means no hangout friends. Because you're not there. You move on in 1 to 8 weeks
● no shopping. Yea, I know, some people are doing it precisely because they want to avoid consumerism. But, most people are used to traveling for a few days to 1-2 weeks max, then coming home. For most of those people, shopping for trickets, clothing, in this far away place is a joy. But, that joy is much harder to come by when you can't go back and stash your loot. All you can do is replace something you have. Buy new shoes and throw away the old ones, etc..
● no crafting / diy / maker stuff - If you're into making things you need tools and storage for materials. Not going to have those living out of a backpack/suitcase. Even little things. In my apartment I have a shelf full of stationary stuff, paper clips, push pins, rubber bands, cellophane tape, masking tap, markers, glues of various kidns. All that is not something you can travel with so if that's your hobby or if inspiration strikes while living that way you're kind of out of luck. If all you make is digital and so all you need is a notebook/tablet/phone then this is less of a problem.
● no stability - it was strange knowing I'd be homeless if I didn't start planning something before the current rentle period was up. I'd arrive somewhere and immediately have to start looking for new hotels/airbnbs for the next stop or two.
It also got somewhat tiring to arrive, look up the sights, and find that to some degree they start to get too similar. Going to an art museum 2-3 times a year is fun. Going to one every week and, at least for me, it started to get repetative. Same with visiting yet another old building. They are all great. But, they're great twice a year, not twice a week.
It's definitely gotten easier though. 12 years ago I had to buy a sim in each location. They sucked and didn't have much data. That's much better today. Free-ish wifi is more ubiquitous than it was then too.
Personally I'd just recommend traveling more often but keeping a home base. I also found that throwing away all my stuff I think was a mistake. Those things I got rid of because they were on my shelves but I never picked them up, I only realized after I got rid of them was that their point was not to be used, their point was to remind me of times, places, and people at the point in my life when I acquired each one. With them gone there is nothing to trigger those memories.

If you want to make your own solution there's one listed here about 1/2 way down the page

As an aside, WebGPU doesn't have this issue or at least has it less. For one, WebGPU can use a single device to render to multiple canvases, something WebGL can't. Another is that WebGPU is mostly stateless making it easier for both the user and the browser.
In my mid 20s I saw Casablanca and was not impressed.
In my mid 50s I saw it again and cried until I trembled. The 20 something me didn't get what the 2 main characters were giving up. The 50 something me with life experience of loves lost by choice and circumstance had a very different reaction.
Saw "Saving Arizona" right after losing my girlfriend. Saw every problem they had as tragic instead of comedy. Didn't like the movie. Some relatively short time later. Saw it again. I was my favorite movie for years after.
