ada -- i was thinking about your work and maybe you should look at the work of Daniel Buren. in a sense, you are doing the opposite of what he is doing. look at his work and think about how his work deals with seeing public space. maybe this can help you to develop different ideas about display and scale and maybe even move beyond 2D. daniel buren has a website: www.danielburen.com, but you can also find plenty of books about his work at any of the UT libraries.
