Clarity is not always linked to telling. Some ideas are flattened when efforts are made to explain or demonstrate. Some ideas need space to work. Some ideas need to be found rather than shown. Some ideas are made implicit by their inclusion. Some ideas only need the suggestion to do their work. Some ideas change once that are shouted. Some ideas require an viewers choice. Some ideas need to be seen in relation to other ideas. Some ideas lose all meaning when you look at them alone. Some ideas are not meant for everyone.
