    I want to make some really big laser etched maps.

There's something fascinating about maps. I particularly love how they have this kind of fractal level of detail as you zoom in and out. Look at this one, I really like the minimalist black and white design.

    .os_maps {
    filter: grayscale(1) contrast(1.1);
    }
    .os_maps_london {
    filter: grayscale(1) brightness(0.8) contrast(2);
    }
</style>

<div id="map" style="height:400px; width:100%; margin-top: 1em;"></div>

These black and white map tiles are from <a href="https://stamen.com/">Stamen design</a>, essentially a really nice style sheet on top of &copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributor data. The rest are OS Maps from the <a href="http://maps.nls.uk/projects/subscription-api/">National Library of Scotland</a>. The viewer is <a href="https://leafletjs.com/">leaflet.js</a>.

In related news, my excellent [co-working space / carpentry workshop / pottery studio](https://www.r-a-r-a.com/) currently has a massive laser cutter which we may or may not keep for the long term.

<figcaption>
The laser cutter can do either a raster or vector. Here is a raster into some birch plywood. They're 10cm square with slightly different settings.
</figcaption>
</figure>

Given the laser cutter is so massive I thought it might be fun to try to produce a huge map. There's a spot at the top of the stairs in our flat that I think could be nice for it. My partner and I have always always lived somewhere in this vertical strip of london so the tall thin shape has some significance.

<figcaption>
A blender render of what it might look like based on a 3D scan of my flat. This took all my very rudimentary new blender skills to put together.
</figcaption>
</figure>

Given how long those took to cut, I'm thinking that I'll split the design into multiple panels so I don't have to babysit the laser cutter for 24 hours.

<model-viewer src="/assets/blog/maps/bigmap.glb" ar ar-modes="scene-viewer webxr quick-look" camera-controls shadow-intensity="1" exposure="1.08" camera-orbit="30.45deg 63.68deg 27.8m" field-of-view="22.88deg" auto-rotate>
</model-viewer>
<figcaption>
Here's a 3D version. I got the scan with the lidar scanner on an ipad.

</figure>

Let's see how that pans out next time!
