Skyfield is very cool. For my wedding, I wanted to give my groomspeople personalised thank you gifts. The idea I came up with was to find or ask for precise dates significant to them each (their own anniversaries, birthdays, special events...) and convert that into an abstraction of the relative positions of the planets on that day using Skyfield: https://imgur.com/l7G0att (and with the moon's orbit if they wanted: https://imgur.com/CYqfLR4).

I then got them engraved onto cufflinks https://imgur.com/bhxJVGo

They were super happy with the result, and we all looked great on the day. I wonder if there's a market for these but it feels a little niche, I'm glad skyfield exists to help projects like these.

Very nice. I love this kind of thing.

I make multispectral Sun images (https://imgur.com/UMQhcw6) for people occasionally based on a time & date, I started messing around with the idea for my son, and then as a gift for a friend and she then helped me get a page up https://www.theremarkablz.com/thesun

It's often for sciency people who have just had a kid, because with the SDO images you can get really close to the specific time of birth.

That is a very cool gift.

While not exactly the same, I got my wife a framed print of the stars over our wedding day as an anniversary gift a few years after we were married. It may be a little niche, but I think there is a market for that kind of thing.
