PEN_SQ  Even the simplest app has to have one bug. This is no exception - the fingerprints are left about a knuckle lower then they should. Other than that, it's important for any system, even without any interest in iPhone programming.

Switching over to the gorilla hand when you run it on a 30" Apple Cinema Display is a nice touch.

Some features to look forward to in the boxed version -

No Hand mode - just leave the fingerprints around.

Drag-n-Drop Smudge streaks.

Adjustable greasiness and color stains, all the way up to "had a bag of Cheetos".

Fingernail growth.

Jabbing the finger if you ram into the menubar too fast.

A "trackpad" mode where the hand clicks with the thumb.

Hand holding a mouse mode. Not any ordinary mouse, but some of the most uncomfortable mice made, such as the Asus Mouse/Flash (google it), and the Apple Puck.
