Examples:
* A single node represents a single mirror. All points off the mirror are drawn with a ring. Connecting such an off mirror point to its reflection creates a [[digon]] or [[edge]] perpendicular to the mirror.
* Two unattached nodes represent two [[perpendicular]] mirrors. If both nodes are ringed, a [[rectangle]] can be created, or a [[square (geometry)|square]] if the point is equal distance from both mirrors.
* Two nodes attached by an ''n'' edge can create an [[polygon|n-gon]] if the point is on one mirror, and a ''2n-gon'' if the point is off both mirrors.
* Three mirrors in a triangle form images seen in a traditional [[kaleidoscope]] and be represented by 3 nodes connected in a triangle. Repeating examples will have edges labeled as (3 3 3), (2 4 4), (2 3 6), although the last two can be drawn in a line with the ''2'' edge ignored. These will generate [[Tiling by regular polygons|uniform tilings]].
