To all those lolkwerk'ing, I'd like to see you explain why his idea is worthy of such a pathetic response.
Primarily because creating this simulated high mavity is, and lets be honest, always will be, more costly than using weights. Prohibitively so currently. If you can find a practical way of doing it then it would indeed allow added resistance to callisthenic exercise, but what's outlined in the original post is far from practical.
