Optical illusion

The dots you see in this blip are actually on the glass door of the cupboard in which the glasses are stored.

However, by focussing on a facet of the glasses inside the cupboard, the DOF makes it appear that the dots on the door are behind the glasses inside the cupboard

And if you're confused...please don't ask me to explain!!

Just to complicate the issue even further there is no green anywhere in the glass or cupboard - this has appeared through using Photoshop's cross-processing function

...and now I am definitely going to bed

Just realised that this one would work for today's February challenge.
