Gestalt- Closure

These images demonstrate Closure.

In A, it appears as though there is a triangle in between the three circles.

In B, it looks like an "S" with a missing center, but can still be noticed as an "S"

In C, there isn't a sphere in the center of the spikes, but it appears as such how the spikes are placed.

In D, it looks like it's a lockness monster type shape, weaving threw water even though half of it is missing.
