funny things

So this is kinda wierd.  I was outside of the RESA the other day going to walk to the Paral-el station when i noticed the stone work on the side of the building.  The façade is made out of limestone I think or sandstone (it looks like sandstone) and there are these little parasititc lichens growing on it.  Well if you look at how the lichens are growing it looks kind of like a cave drawing of a landscape.  It is true.  I dont have a picture yet but just you wait i am going to get one and post it real soon.
