I tweaked the final project in this chapter to add a gravitational body. It's super sweet. I am loving the things I'm learning with this stuff. It's simple, but super awesome.

Good stuff.

The previous chapter (three) had example code that used one of the author's "util" (utility) functions that hadn't been introduced yet. This is bad form. That function (and its sister function) have just been introduced in chapter four. Adding this to a growing list of little problems this book has. Otherwise I'm learning a lot and really enjoying it!

Just finished chapter three. So far there are a few errors splattered throughout the book and examples, but it's not too bad and it gives you a chance to learn even more by finding and fixing the problems.
