Etch A Sketch revived as a mobile phone game

Hearing about an Etch A Sketch game brings back childhood memories when I tried to draw pictures by removing aluminum dust. Good times, but I don’t have any idea how FreezeTag plans to recreate the feel of the toy without turning dials. Using arrow keys just isn't the same for me. Their Etch A Sketch game does have something the plastic toy doesn't, an arcade mode with a 100 levels. Interesting… but wouldn’t an Etch A Sketch game on the DS make much more sense? On second thought maybe not, using the stylus would make it way too easy.
