Attack of the Triffids!

I was sitting in my container garden down on the back patio, enjoying a glass of cider, when I noticed this knot hole in the fence and realised that I could see something through it. So I snapped it.
To my overwrought imagination it looks like an Alien invasion through one of those breaches in the Space/Time Continuum, (you have to be a Star Trek fan to get that last bit)
Or maybe through an Intergalactic worm hole.
Who knows?
Who cares?
They're coming to get me anyway.
Now, where did I leave those secateurs?
