To get started, conjure up a past that isn’t yours. Write/type the details. Then, find someone to interview you - but no talking - the interview is silent, you will have to exchange notes. Consider what materials you will use for note taking as such materials can/should reflect the personality of your invented past and/or time and place of interview. Use the written words to create a visual piece that is reflective of the past you invented and/or the time and place of interview and/or any other ideas that emerged during the inventing and interviewing process.
Make sure to check out the artists listed on this blog under "Conversations Artists". These artists will expose you to the use and interpretation of the written word.
