Symmetry in small amounts 

Here in this image it showing that the use of symmetry doesn't have to be the whole room it can be used in small amounts.
The symmetry however in this image is used in circular design.
Here you can see the circle table with the chairs placed perfectly around the table.
Also the circle lighting above the table is placed in the middle of the table.
Here the visual divide is very obvious like other images I have posted but the divide is there.
