The Peabody Award-winning “Studio 360 with Kurt Andersen,” from PRI and WNYC, is public radio’s smart and surprising guide to what’s happening in pop culture and the arts. Each week, Kurt introduces you to the people who are creating and shaping our culture.
Listen to the show on your local public radio station or online.
Studio 360 in Japan is supported, in part, by the Freeman Foundation and the United States-Japan Foundation.

You asked about people making art on their cellphones. 90% of photo collages and panoramas on my Flickr were shot with an iPhone.

Some, like these two sets:

Panolab http://www.flickr.com/photos/p0ps/sets/72157616627038997/
were created entirely on the phone – uploaded from it as well.
In addition, I’ve been using the iPhone to shoot and post “10 Second Videos”:
