  11. Class Project • Done in pairs (Except Alejandro :P) • Goal: Use what you’ve learned to do something cool (basically) • Expected difficulty: More than a lab’s worth • But from scratch / without my help! • Marked on: Difficulty, appropriateness, scale, good use of techniques, presentation, coolness • Ambition is appreciated, even if you don’t succeed: feel free to bite off more than you can chew! • Process: • Pair up (default random) by Wednesday • Decide on a topic (by June 9th) or let me assign one  • If you need data or get stuck, I will (try to) help out • Deliverables: 10 minute presentation (June 23rd) & 4-page report
