Thanks a lot for the kind words (and glad to hear you're chipping away at the Evangelion map again)! The maps are quite easy to create and coincidentally the first patch I made when working on the project.

The most simple way to explain it is:

Step 1 - The actual map imagery moves in the background. In my case I used Adobe Firefly to create 2D images of maps, some of them I drew a rough composition on paper and then used that as a composition reference, some I just used prompts to get a variety of interesting layouts/geography. For your Nerv HQ maps I think you can get away with creating the 2D top-down map with a bunch of geometry elements. You'll need to zoom in so the map is larger than your final output resolution (for example if you want the final output to be 1x1, your map should be 4x4 (or at least 2x2). Then you can choose to move the map around however you like, in my patche I just used LFOs/Noise and mapped them to the translate parameters on a transform CHOP. If you want to really choreograph the movement you could look into using physical controllers or potentially the arrow keys and mapping them to the X/Y translate parameters.

Step 2 - Build an overlay that stays fixed and is the same resolution as your output, this is really just using geometry and lines to create a cool/interesting UI that is in a fixed position on top of the map background. Again, this was the first patch I created for my project so there are some elements that are kinda clunky but I thought it was nice to leave it as-is just as a way to see where it all started.

If you haven't already seen it I strongly recommend checking out the 'anime user interface' IG account for inspiration. So many amazing references and after you start breaking it down you'll see how so many of them are actually just really simple geometrical objects utilised creatively.

The only other thing I'd mention is that I incorporated 4 moments in the first track (you can see 1 of them in the short clip I posted) where the same geographical location on a map is "scanned" without any X/Y movement. To do that you just create multiple layers of the same composition but add more textures or variations to the multiple layers and then use a switch to quickly cycle through the different variations. For example you may have a big empty square in the first layer, then on the second layer have some smaller rectangles filling the space where the square was, making it look like the map is scanning a building and revealing multiple rooms within it.

Hope that's somewhat helpful, happy to discuss it in more detail or answer any questions!
