==Strict still lifes==
A '''strict still life''' is a still life that is either connected (i.e., has no [[island]]s), or is such that removing one or more its islands destroys the stability of the pattern. For example, [[beehive with tail]] is a strict still life because it is connected, and [[table on table]] is a strict still life because neither of the [[table]]s are stable by themselves.
