In checking out these utterly cool aircraft (my favs the Gravity powered aircraft flies with no fuel and VTOL AirBike) I really became obsessed with GizMag. Between GizMag and Make: (which has a blog) I could really get depressed over not having enough money for these cool toys or enough live span to play with them. I guess in addition to these two I need to spend more time at Kurzweil AI learning how to live forever.
