NASA Sounds

Maybe it's just me but I found these released NASA sounds quite enjoyable to listen to. One of my favourites is Atlas V: Launch.

The Khan Academy

I love what this guy is doing: Salman Khan has recorded over a thousand ten-minute lectures on every topic in the K-12 curriculum (and quite a bit beyond that), and they are all free. There are tons of math lectures. He is doing it primarily as labor of love, not for profit. I hope he gets very rich off it anyway; he deserves it.  Amazing and inspiring to see. Check out the Khan Academy.

Bridge Construction

I'm now addicted to the Bridge Construction where you make a bridge that doesn't clasps when trains go on it. Games like Bridge Construction Set for 20 bucks and Bridge Building for free but is not nearly as good. Photo here.
