Mark Jardine on designing Convertbot:

When you press the FROM or TO button, you can see the selected tile slide out from behind to the top position. In this world, the selected tile needs to slide back behind the button it belongs to before any other action can take place. I’m assuming most people never notice and others probably don’t care, but I think the extra step contributes to the believability of the world I’m trying to create in our apps.

They made a unit conversion application, and Mark is talking about creating a “world” in his application. This is how applications should be designed.
