More than in previous years, the public face of Apple’s Worldwide Developer Conference is centered on a single product. Unsurprisingly, this year’s focal point is iPhone.So far (35 minutes into the keynote), Apple has described nothing that hadn’t been covered in its March press event on the iPhone SDK. However, Apple’s chosen third-party iPhone developers have made a lot of progress. Sega, eBay, Loopt and TypePad showed applications that will be available at the launch of Apple’s AppStore. That tease–“at the launch of Apple’s AppStore”–is the consistent close of every demo, setting up that launch date as Steve’s punch line.[ Learn more about making the iPhone fit in the enterprise in our special report. ] Sega has spent a lot of time since March getting its Super MonkeyBall. It’ll be $9.95. It uses iPhone’s accelerometer to steer a ball through what amounts to a miniature golf course where the golfer is trapped inside the ball and can fall from the course to his death.AP and Loopt use iPhone’s location services, which use cell tower triangulation rather than GPS, to deliver local news and personal location-based services. AP supports uploads from external users.Pangea Software ported two Mac games: Enigmo and Cro-Mag rally. Like Sega’s Super Monkey Ball, these games use OpenGL and iPhone’s accelerometer. They’ll be available for $9.95, yes, when the AppStore launches. Cow Music is a one-man developer who created a limited, but cool, subset of Garage Band. Major League Baseball will have an app showing scores in real-time, with self-scaling video of games in progress.Modality showed reference and quiz software targeted at medical students and physicians. Another medical industry software shop, MIMvista, demonstrated medical imaging that allows viewing of multi-slice PET images. MIMvista can construct a 3-D image from these slices and present it, rotating, on iPhone.The last highlighted developer, Spain’s Digital Legends Entertainment, started with the SDK two weeks ago. They demonstrated a very pretty 3-D adventure game, Krull (sp?), that stretches embedded OpenGL to its limits. That’s it for the demos. I’ll push this out before the keynote moves on.
