Mould on Signs

Okay I know this is weird, why would any even slightly normal human being find this sort of thing interesting, but, and hear me out here....this is beautiful, sure it's a product of moisture and not enough sunlight,, and it may be harbouring any number of diseases, but, the colours, the shapes, the organic nature of the blooms, trust me when I say this is amazing.

I mean imagine these 10 feet high in an art gallery - you would be amazed.
