Last week's assignment went well, so one of your options is the same as last week's.
Option #1: Take some small fragment of Danielewski's text -- a paragraph at most. It should be something we have not discussed in class, _or_ you should have a completely different take on it. It must be a passage which has some larger significance, hopefully one not immediately noticed or understood. Follow that passage (or shape, or symbol, or whatever) in detail, using it to formulate an argument that _just_ looking at that passage, we can/should understand the book as a whole in at least a subtly different way.
Option #2: Do a rough rough draft of your final project (yes, you need to do your proposal first) - at least 2 pages worth, the same as any other formal blog entry. Those of you who aren't doing a formal blog entry this week can certainly post a rough rough draft as an informal blog entry.
Other things: If you haven't done a project proposal yet, do so before class on Thursday, if at all possible.
