• If yes, then let's work with them today. Assignment #6/7 will be due on Feb 17th. Also what do you think about changing assignment #6/7 to 10% of your grade (down from 15%) and assignment #3/4 to 15% (up from 10%)?
• If not, then let's work with them this Saturday, add another week to assignment #6/7 (due Feb 24rd), and include an installation as a part of the piece.

• If you are doing a presentation instead of a paper, email me the artist you want to present on by next Tuesday (Feb 10th)
• If there is a conflict (more than one person wants to do a particular artist), the first person who gets me the name of their artist in an email wins. The other person will have to chose someone else.
• This does not apply if you are doing a written paper
