If you've missed World of Goo in one of its many iterations over the years, there's another chance to play the superb physics puzzler. It's now available on your iPhone or iPod Touch—the iPad version has gone Universal. It's all of $.99 in the iTunes App Store, which when coupled with the ratings in the store (98 five star ratings, as of this writing, 11 anything besides five stars), should be enough to get you to drop a hot buck.
