The PADD from Star Trek: The Next Generation is credited with predicting the existence of the iPad 20 years before it hit the market. Now, you can turn your iPad into the all purpose computing device the crew of the Enterprise carried around by downloading the official app. Imitating the look of the LCARS (Library Computer Access and Retrieval System) user interface that all of the computers on the TNG Enterprise used, complete with appropriate sound effects and voice prompts from a soundalike of the original computer voice (the late Majel Barret Roddenberry), the app also includes a database of ST:TNG information including alien races, ship models, locations, tech and a detailed episode guide. Connect with other Trekkers via Facebook and Twitter integration that link with official pages and accounts. And if you want to use it for desk candy, there are two self-running diagnostic modes with a schematic of the Enterprise NCC-1701-D. For true nerds, interface designer of the Starship Enterprise and the author Michael Okuda, along with his wife, Denise, of the Star Trek Encyclopedia were involved with the project. Back when the PADD first appeared on ST:TNG, none of us imagined that today we d be able to hold the real thing in our hands. But the Star Trek PADD app, running on your iPad, is an actual miniature, handheld, touch-sensitive, 24th-century-style computer screen, says Okuda.
