There's so many but one that sticks out to me personally has been Hero of Bitcoin Demo for the Gameboy (and Android + Windows).
It's so well polished, so well done. It educates as well as entertains and I've already met Max Kaiser and Stacy too!
Absolutely what I think the ecosystem needs, creative outlets for their Bitcoin love.
