Gorge on Retro Japanese Robots by Downloading This $3 iPad App

There's no clever functionality, no swish design—just reams and reams of vintage Japanese robots for salivating over. It's like a flipbook of otaku porn—only won't attract too many stares on public transport.

It's based on a Japanese book from 1988, cataloging the robot of collector Teruhisa Kitahara, who is "internationally known as the top ladder of Tinplate Toy collector," according to the app's description.

Beautiful large photos of each robot, along with information and even videos of them wound up and hobbling along —this could keep an enthusiast happy for hours. It's $3. [iTunes via Recombu]
