Phone Arts has been around for awhile. It has, like many tumblrs, a highly specialized focus. In this case, it is “an International collaborative project experimenting using only the mobile phone as the medium to create unique compositions. They explore the boundaries of the phone to create graphic illustrations and designs.”
Many of the images are various kinds of abstractions, some apparently created with pure color, others by manipulating photos.
The frustrating drawback: there is no, as in zero, none, nada, information about the images – about which phones or apps were used, or when they were done. No digest of information, no text about it. You’re forced to only, and simply, look.
