This is a result of a group in harmony with people who are in love with what they are doing. When you like the subject, and pour what you have into it, this is what comes out. I'm sure this wasn't tiring for them.

Make no mistake, this is a very high achievement, and is very rare in both private companies and research labs. It's a very hard point to reach if you don't like or care about what you are doing.

Kudos to them.
