I'm on my way to Amsterdam for #NOAW. If you like OpenStreetMap, open data, and other cool things, you should try our web version of "Map to Poster": https://poster.54gradsoftware.de/. With this software, you can create attractive posters and postcards of cities.
It is a TypeScript and web GUI version of https://github.com/originalankur/maptoposter.

This is also a great example of how you can create beauty with open data. Here are some examples:

@sabrinkmann For what it's worth, it looks like jobs take longer than the default timeout, so generation reports 504. I see jobs are getting through, as there's a poster for Nantes that's just been generated and is showing in the Recent Posters list; it's just a reporting issue as the frontend evidently isn't waiting long enough.
@Two9A Thanks for the information. Generating the images can take some time as we do not have a full copy of all the OSM/X data on the server locally. As this is a side project and we only experience high usage when we promote it on social media, the best advice is probably just to try again later.
