Bricks

I spotted this stack of bricks in a back street and it really appealed to me.   The bricks on the right side have managed to stay upright but the ones on the left are nonchalantly leaning to one side.  I like the different colours of the bricks; there's a couple that are covered in green mouldy stuff and a few along the top that are black. I'm slightly intrigued as to where they originally were to have such a mix of colours.
