  • I wrapped up phase two of Easington. We completed the beta of our interactive game-like thing that we built to explain the output of that phase. The prototype evolved a lot during the phase. Probably the best thing that happened as it progressed was that things I’d initially described in text were extracted to state. That is to say, we made it more gamelike: rather than describing other possible outcomes of an action, why not find a way of letting the user alter the state of the world, and then see what happens when they repeat the action?

    It sounds obvious when I write it down, but when I’m head down in the code, it is sometimes hard to have that high-level picture. This is one of the values of weeknotes: acknowledging what I missed, and writing it down so I don’t forget. Making the prototype more interactive - adding new interactions, and making it respond more richly to them, turned out to be the right answer every time. Something to remember for the future.

    This phase of the project has had me thinking a lot about propmaking, and its relationship to protoyping.

    Props in films aren’t just one thing. Think about a prop like, say, a lightsaber from Star Wars. A single prop lightsaber will likely exist in several forms, including:

    • a “hero” prop, that’s seen in close dramatic scenes. Made of realistic materials (metal, plastic, wood), full size, detailed. Something an actor can act with, and respond to. Something that will look good on camera.
    • perhaps: further hero props in different states: with the blade extended and retracted, for instance, or “damaged” and “undamaged”.
    • perhaps a separate functional hero prop for specific purposes. Imagine a close-up scene where we see the hero dismantling their lightsaber and repairing it: that “dismantalable” prop might be entirely different to the hero prop seen most of the time. (It might even be a partial prop - just the parts you can see in shot, and extra things to make it work also attached)
    • stunt props. These look almost identical to hero props, but are usually made entirely of foam rubber, and cast from the hero prop. These are used, as the name suggests, for stunts, where the object might be bashed around, or come into contact with an actor at velocity. They also end up being used for scenes where there’s any rough handling of a prop that might damage the prop itself - being thrown, or dropped, for instance. And frequently rubber props will used for background action, made en masse to give to extras, or used when the hero prop isn’t strictly necessary - when the lightsaber is hanging from the hero’s belt in a scene where it’s not really used, for instance.
    • once upon a time, props might have existed as scale models - a miniature lightsaber on a stop-motion puppet, for instance. Scale models tend to be more common for large objects, like vehicles or buildings.
    • the modern equivalent of a scale model prop is a CG version of it, to be used in computer-generated visual effects. The prop has a digital double, perhaps made from a 3D scan of the object.

    And for some of those props, on a large film shoot, there will be duplicates and spares.

    I’ve been thinking about the way one prop exists in multiple forms, and the different roles they all serve, because of all the different kinds of prototype I’ve built so far on Easington.

    So far, we’ve made real working code and tools (out of Python/Javascript and Docker/Cloud Run, as well as modern front-end web stuff); an interactive, explorable prototype pocket world; browser-based prototype UIs; clickable prototypes in Figma; and sound and video prototypes made out of samples, synthesis, and video in tools like Ableton Live and Hitfilm.

    And all of those prototypes are very, very different.

    • Our working code makes a useful point about the current state of things, and lets other people explore the idea. But it’s not in any way production ready, and it falls apart a little if you don’t use it the way it’s intended. That’s our close-up, working-for-one-task prop.
    • Our clickable mockups are like stunt props: they look highly convincing, fulfill a hugely important role, are highly robust, but the second you touch one you’ll discover it’s fake.
    • Our video and audio demos are a lot like CG: entirely convincing, we can do whatever we want with them, but 100% fake - and not even interactive.
    • Our interactive gamelike is a bit like a scale model: it has not just look/feel but logic as well, albeit in a highly constrained and limited way. It makes sense in its own little pocket universe.

    Like props, none of these are exactly ‘real’, and none of them work outside the world of the project. But they all serve useful purposes, and like all the different prop lightsabers, they all work together to tell our story. Our scale models, clickable mockups and VFX are made convincing by the fact we’ve also shown genuine, working code, but in a rougher form. And they wouldn’t have the same impact if we didn’t have that “close-up” prototype.

    The mockups and scale models help us invent and imagine, and help people using them imagine how the fragile working code might feel in the world, and in the near future.

    The other thing I find useful about enumerating the different types of prototype we’re making is it helps me understand what their individual value is - and when they might be considered “done”. Because they’re all fulfilling different roles, they have different completion criteria. Some need to look very good; some need to function correctly; some need to be somewhere in the middle. Understanding what the prototype is trying to achieve in terms of its role, not just its functionality, helps me think about the right material to build it out of, the right level of detail to furnish it with, and when to put it down and move onto a different kind of prototype.
