When someone new asks to see what an iPhone can do, all of us have a list of apps prepared to wow them. Some of these apps may be useful, some may be beautiful, and some may have changed our lives. Star Walk is a gorgeous, dynamic application that, while it may not be technically useful to some, will tease your eyes skyward on clear, starry nights.

Gravulous is a space themed hybrid of pool and marbles with planets as your playing pieces. However, in the middle of the Newtonian planet-cracking gameplay, a relativistic entity, the Gravulous, is waiting patiently to take advantage of even your smallest mistake.

What a great game, perfectly simple and very fun.
