5x5s and 20x20s: Traditionally, attendees are invited to share digital images during these popular evening slide shows to let us know who you are and what you do - or to show us your latest project! The number of these presentations has been steadily growing year to year, and this year we have more time constraints than usual, so we encourage all attendees to bring your project or presentation in a printed 11" x 17" poster format, which will be displayed in the conference space. We will also draw names out of a hat for an hour's worth of slide show presentations on Saturday night for those who want to actively present in addition to displaying a poster.
- nightly "happy hour" networking ...
