Through a glass, but not darkly

The Christmas tree lights mostly through a glass with dimples. In the main image the glass is on its side, in the extra it's upside down showing the Christmas tree shape. For today's Abstract Thursday with optional theme 'using tangible visible aids', meaning make an image through something like glass, plastic or any other transparent material or using reflections or refractions on shiny materials to make something abstract of a photo subject, to create an impression of your subject. Today's tag is AT339, please tag your entries with that so I can find them on Boxing Day :-)

Yesterday's Blip was mostly invisible because of Blip bugs, but thanks for any views and comments :-)
