Ha! That's pretty cool.

My first thought with this card was that it could be "gamified" into something that kids would probably love. A clique-y, social thing where kids could "pour" some of their fluid into another's card, with NFC or something. User preference colors that don't change when "poured" could help indicate how many different people have interacted with your card.

But enough spitballing. There's no killer idea there. Just something I'll be amused to see show up as a value-add for some other kind of toy, or whatever.

Stuff like that is dead now btw (yes, it makes me sad too). Kids have iPhones; the idea is great but can just be an app. Which tbf makes more sense because you get the benefit of imu & everything else for that behaviour.

Remember those little LCD cube block toys with the stick dudes that lived in 'em, then when you plug 'em together they interact? Those were the days.

Liquid Pokemon Eggs and Sperm! Gotta catch it all!

Then you can lay the fertilized eggs at any GPS coordinate to gestate and hatch later on.

That could start a whole genre of AI (Artificial Insemination) Life Simulation games.
