Here are the books that people chose (preceded by the count). It's a great collection; evidently Gatsby is very popular.

Graded gently, since the purpose was to encourage you to do some exploring and learning. A fair number of people didn't do anything after the "required" steps. I also had to fix a few places where some variable wasn't initialized or a module hadn't been loaded, or remedy some minor syntax error.

Thanks to all for comments on the lab. In some places the instructions were not as clear as they could have been, and it was perhaps too open-ended at the end, in the sense that there wasn't enough guidance about what to do beyond the required steps. But I hope that overall it was helpful, and perhaps gave you some ideas of how computing could be useful.
