Coming to us from France, ARTags is an AR drawing application, that apparently makes it very easy to draw nice looking pictures on your mobile phone and add them to your current location. Though it's quite new, already more than 1500 pictures were drawn using this app all across the world.
But that doesn't make it special. What makes ARTags special is the fact that it's a cross platform app. That is, the pictures are visible using Wikitude, Layar and Junaio (though I had a bit of a problem finding the right channel on Wikitude). Instead of creating a new browser application, or integrating within only one of the above three, the folks behind ARTags decided to have a presence in all of them. That's absolutely the right decision, at least at this stage. I certainly hope that other app developers will follow.
Now, if only someone invented an app to make its user better artists.
