I wish I had the time that I had back when I was in high school. The time part doesn't have anything to do with the skills though. At that age I would have never been able to do a similar thing - at my age I would probably struggle, but with enough time at hand I might achieve half of the project.

This is what makes this whole thing exceptional: this person is very talented and is using his free time to do great things - I appreciate that.

If my initial comment sounded like I was bragging I would do it too if I had more free time, it wasn't my intention. I actually am jealous that I get to spend less time on my side projects and I envy those who can build such cool stuff.
