Are there any easter eggs in iOS?

[BdR]

I've always liked easter eggs and hidden stuff in programs and videogames. You know, intentionally hidden features just for fun. Almost all programs I've made since the msdos-age contain at least one hidden feature.

So I was just wondering, easter eggs are pretty common even in most operating systems, see this list. But there don't seem to be any known hidden features in the iphone operating system.

Aren't there any easter eggs in iOS or are they just not discovered yet?
