Project 2

It's time to start thinking about another project. Project 2 is due the end of the semester witch is December 7th. You have 5 weeks to complete the project.

Here is the schedule for Project 2:

• 11/16 idea drawing and precedents due
• 11/30 working prototype due (part of final grade)
• 12/14 Project due / presentation
• 12/19 Documentation due

It is the final project for this class but don't think too much about making an "impressive" project.

Keep it

• simple

  Idea drawing and precedents for Project 2

  For next week be ready to discuss;

  • ideas and drawings of your project
  • Precedents and inspirations
  • potential chalenges of your project

  Presedents and inspiration does not have to be art works. It can be simply things and phenomena around you that interests you. Be specific!
