Can we have more in game Easter egg?

[khun_poo]

 How about put some randomly generate "easter egg" thing in the game?

For example, if the colony have grow rice more than 20x20 tile and leave the rice un-harvest. They might create a crop circle overnight and disappear sometime later.

Or maybe a giant shadow of unknown creature will rarely appear in the river or deep water when there's aurora.
