Decker provides a set of four "animated patterns" which can be used to add subtle (or eyeball-destroying) effects to drawings and help make important objects stand out in 1-bit.
Did you know these patterns are customizable? Each animated pattern is defined as a sequence of up to 8 indices of other patterns, including the solid colors at index 32-47. The animEdit contraption provides a simple editor for these sequences, as well as a quick reference tool for determining the index of a given pattern.
