 ## Credit
 This handout was used in prior versions of CS 41, where it was unattributed to any individual person. Context suggests that it was a pool of ideas from a bunch of former CS 41 Course Staff. Moving forward, this document will function in that way: as a collection of project ideas from all staff members.
