8-Bit Pop-Up Cards
Two ways to create your own: firstly, a tutorial from Mini Eco to create your own Space Invader and pixel skull:
Hello! Remember that pixel heart card I made a while back? Well it has been one of my most popular tutorials to date so I thought I would add another few designs to the collection. Meet ‘space-invader popup’ and ‘skull popup’
… You definitely need a craft knife (and a steady hand) to make these cards this project is only really suitable for adults or teenagers.

If, on the other hand, you would like to design your own, there is a piece of software that has been around for years called Pop-Up Card Designer from Japan:
