MonoMonday - Optical Illusion

Hubby and I spent the day at the local Spa and sauna. It was beautiful in the outside pool surrounded by snow with a few snow flakes falling. Fortunately, the water is very warm as are the saunas. 
I had to play around with some still life at home this evening for my blip as cameras are not allowed in the sauna area. This is probably a true optical illusion rather than a photographic one but though it made a nice mono.
Thanks to Marlieske for hosting,
