I have a bookmark for it, and whenever I want to kick back a bit, perfect.

However, I've noticed that it has a tendency to go blank (i.e. fail and stop working) when multiple colour spectrum triangles are in play and in particular when they are on top of each other.

I'd really like to see some additional objects to place into the machine.

One other problem I have is that the "perma-link" button doesn't seem to do anything. When I come back to the URL, my machine isn't there.

    function solveSecondOrderODE(b, c, y0, dy0, dt, tMax) {
        let t = 0;
        let y = y0;
        let dy = dy0;
    
        while (t <= tMax) {
            console.log(`At time ${t.toFixed(2)}: y = ${y.toFixed(4)}`);
            let ddy = -b * dy - c * y;  // Compute the acceleration (second derivative)
            y += dy * dt;               // Update position
            dy += ddy * dt;             // Update velocity
            t += dt;
        }
    }
    
    // Example usage:
    // Constants b and c for the damped harmonic oscillator
    const b = 0.5;  
    const c = 1.0;
    // Initial conditions: y0 (initial position), dy0 (initial velocity)
    const y0 = 1.0;  
    const dy0 = 0.0;
    // Time step (dt) and maximum time (tMax)
    const dt = 0.1;  
    const tMax = 10;
    
    solveSecondOrderODE(b, c, y0, dy0, dt, tMax);

I work for a major University. The only major numerate discipline for which we do not teach programming to undegraduates is Medicine, and my guess is that Medics are already completely buried by the tremendous amount of stuff they're expected to have at least some knowledge of to do their eventual jobs, without us showing them how to make apps.

Like sure, if you come here to study Fine Art, we don't (by default) teach you to write software, but if you come to learn like mech eng. or electronics or chemistry or something you're going to be shown how to write software. You can probably flunk that in most of these subjects and still get a degree because it's not on your critical path, but we tried.

These are not software engineering courses. You're not going to learn how to be in charge of a major software project, you won't learn how to design software, nor even stuff like CI and revision control - if you try to scale what you learned in one course as a Biologist into a Chrome-sized application that's going to be a disaster, but you've written software, you know what a loop is, what a variable is, and so on.

Great example: Space Engineers, a very popular game in which you can build ships, bases, etc. with an incredible consideration for automation, moving things around, etc. One of my favorites. But the game intentionally (1) limits the top speed of all entities to 100m/s, (2) doesn't actually simulate orbital mechanics despite having planets, and (3) forces you to construct things on a 'grid'. All of these constraints are arguably shortcomings, but they also enable the physics engine to live and collisions to work.

Also, what you're asking for is very hard to do with physics engines as they exist now. Simulating a bunch of non-static elements like that is incredibly expensive.

As if this is not an absolutely breathtaking creative accomplishment, especially so consistently and after so many years!

I agree with another commenter that it probably does get easier with experience, but nevertheless impressive.

Just programming one of those interactive comics must be quite a challenge, to then add the story, the wittiness, depth, etc is what blows me away.
