Did you know that ping-pong, once upon a time, served as the ice-breaker between Communist China and the United States in the 1970s? It's true: the U.S. and China sent ping-pong players to each others' countries, which paved the way for Richard Nixon's diplomatic visit to Beijing in 1972. In short, ping-pong helped change the world, and now you can play it on your iPhone with World Cup Table Tennis.
Contrary to popular belief, architectural wonders of the 20th century aren't painstakingly planned and constructed over months and years. They're built like sandwiches in 45 seconds. That's what the iPhone game Skyscrapers would lead me to believe, and I see no real reason to doubt it. Taking the addictive formula presented by prize-bearing amusements like Stacker, Skyscrapers puts you at the forefront of tower building technology. Who knew that you could put up buildings just by tapping the touch screen? Ahh, the wonders of science.
