It's an empty vending machine space.
I admit this week's MMO was perhaps a bit obscure.
A few weeks ago, the snack machine at work was almost empty. The spirals caught my eye and I thought they would make a good abstract. The next morning, the machine had been restocked.
So I decided to wait until a Monday occurred and the machine had an empty space so I could use the idea for my MMO shot.
I know it was probably unfairly difficult, but I still liked how the abstract turned out.
