Nothing for tonight.
I talked with David today, and he has some really good ideas for early puzzles. I can begin to implement them, but I would like it all documented to ensure I don't miss anything.
Unfortunately I didn't get anything coded. I was researching an idea to make asynchronous programming better, when I got side-tracked and started researching Go. But enough of that. It's time to sleep, and maybe imagine some fun and interesting physics puzzles! :]
