Sesamouse also sends the position of each finger as touch information (known to Cocoa developers as a set of NSTouch objects) that can be recognized by more advanced multitouch apps. Users can practice gestures and see how their fingers have been recognized above Sesamouse's own application window.

Because Sesamouse does rely on some undocumented system features, Calf Trail is releasing it as a free utility in hopes that it will still benefit both users and developers of multitouch-aware applications. In lieu of donations at this time, Calf Trail is encouraging users to contribute directly to help Haitian small businesses rebuild via a link on the Sesamouse product page.
