The Meaning Galaxy. A shared galaxy where every star is a word someone wrote. Words come to you one at a time: answer with the first thing that comes to mind, and your answer becomes a star linked to the word you answered. Say a word first and its star is yours. Whenever someone says it again or goes on from it, light comes to you. Once every three hours, breathe for a minute and light a word of your own.
