Last Clock for iPhone / iPad

Today I found on lastclock a rather nice free app for the iPhone and iPad where one vertical camer line is user per second to make a hand on the clock.

Sounds complicated?

See this video:

Just like any analog clock, Last Clock has three hands: one for seconds, one for minutes and one for hours.
The hands, however, are made of a slice of live video that gets scanned to the clockface. With different refresh rate for each hand, the three time circles reflect the rhythms of the space at different temporal resolutions.
