On the Tuesday after spring break, we'll continue with our first crit. Please volunteer to present your design to date, or you will be "volunteered".
Whenever one starts working on a project, there is always a tension between implementing more and leaving design decisions open. In computer science, we often commit to design decisions too early in favor of implementation. I encourage you to delay final design decisions on at least the visual front end of your app until your second crit. If you start coding now, focus on the functionality in the back end. We will continue to critique your visual and interaction design for several more weeks.
