Famicase! I love it! If you're new to the word, Meteor in Tokyo have an annual exhibition where artists from around the world dream up an interesting/funny video game and design a cartridge for it, even though the game itself does not exist.
It's been going for a very long time; this is the 20th successive year I've covered it, and for every one of those instalments it's been a blogging highlight of the year for me. I love all of these little ideas, and want all of them to be actual video games.
If you're in the neighbourhood you should absolutely pop in, as these pieces are all live and in the flesh, actual stickers stuck on actual cartridges. Since most of us aren't in the neighbourhood, sadly, all that's left is to browse the complete online gallery, of which there are just a handful of highlights posted below.
Oh, and Meteor are also selling books showcasing every submission if you'd like to flick through the designs on the couch!
