This is my favorite [1]. These are a fun exercise to program yourself. Fairly straightforward but also insightful and easy to create fun variations with.

Interest qualia experience I noted.
I “clearly” see lots of dots appear and disappear. It feels direct and unassailable that I am seeing dots. But I never really see a single dot appear and disappear. (Without making a very selective effort.)
Clues like that suggest that the qualia answer has mechanistic explanation. The signal saying that we see something, directly and clearly, and actually seeing something, are separable.
Which is true for recognition of a previous experience (Deja vu), knowing (unquestioning belief), etc.
We experience certainties and experiences we deem direct, that we often attribute to reality, but the measure of certainty and directness themselves are just other signals only approximating or filling in (usefully confabulating) what we think they say.
Our experiences are absolutely full of invisible simplifications, internally created opaque illusions, of not only information, but meta-information.
They work as efficiencies because by design we do not have the natural ability to perceive or question them. No natural inclination to seperate seemingly deep experience from actually sparse internal sensory and meta status representations, or representations from reality (whether internal or external).
This (along with ibniz) was one of my inspirations for https://c50.fingswotidun.com/
Using a stack based expression approach makes it easier to design images at the cost of being less flexible computationally. I have often pondered enhancements to make it more capable,and indeed Turing complete. Forth style word definition would work, but I also have a soft spot for state machines.
Little toys like these are things I would recommend everyone have a go at. I have quite enjoyed https://tixy.land/ and https://www.dwitter.net
Very impressive! In fact, I have come across your website before and I really like how sophisticated the demos are. Thanks for sharing.
I'd like to take this opportunity to share my own tools that are along the same lines:
https://susam.net/cfrs.html (Turtle graphics but with only 6 commands!)
https://susam.net/fxyt.html (Tixy-like but stack-based instructions)
To see the demos, click '?' and scroll down the manual.
I'll share some of the interesting ones I found!

I forked a fork of this and added extra functionality, including rating and sharing machines, variable simulation speed and canvas size here: https://aesort.com/Turing-Drawings/
It's interesting how some of them halt after a while and some of them don't. I wonder if one could figure out which ones do and which ones don't?
None of them halt, since no halting state is ever introduced into these canvas dwelling TMs :-(
I think GP is actually asking whether we can determine if one enters a steady state, i.e. tape no longer changes.
You are kidding, right? [0]
It was a (not particularly funny) joke.
I thought it was great :)
These are FSMs though, as the tape is finite.

Is it possible to work backwards and take a video and turn it into a turing machine using this format?
I made Langton's ant!

This is interesting, looks like different patterns at different levels of zoom.

A lot of the style of images this creates are similar to Cellular Automata. Especially when you have a piece of information move diagonally across the screen.
Why does this look like a perfect representation of TV static?

I dunno, I took one look at it and thought 'this clearly wasn't influenced by the Cosmic Microwave Background at all! I can tell by the pixels'.
TV static is random. This is basically a pseudo-random generator.
Very impressive! There is something earie and disturbing about the animation, some primal instincts triggered.
some of them, somehow, look depressingly similar to out world, i feel uneasy watching it being destroyed
The "rapids" example is impressively natural and organic looking.
Very cool! Stumbled upon this curious ‘phase separation’. There’s something natural and familiar in the chaos, complexity and decay.
