Interactive e-cards -- Who remembers them?

I feel like a majority of them are straight up lost nowadays (Unless people still have their old emails), I remember this 3D one where you were a pizza delivery person in the dark and you'd carefully click your way to the person's house, and when you opened the door they mooned you XD Anyone remember that one or similar variations of that? I know a lot of e-cards were made in flash but idk how many of them were 3D and interactive like that, it's one of the main things I remember from that time
