Great! Where's the source?

I'm not going to complain about the price, because if there's a market that pays that price then they should charge it.

I'm not going to snub their project because I could write it myself.

Instead, I want to look at their source code and compare their techniques to what I would do and what others have done, and congratulate them for their work. So congrats!

Source, please!
