waiting for a delayed flight, using a new natural media simulator for
the iPhone.
This one is called Layers, and where it differs from my standard  
painting app (Brushes!) is in it's offering of Photoshop-like layers.   
You can paint on a single layer, add new transparent layers and paint  
in them, kind of like painting on panes of glass stacked one atop the  
next.
It has a few quirks and bugs, but it is a remarkably well executed app.
I'll write a proper review soon. In the meantime, check it out!
