So Zohaib Sibt-e-Hassan created these Moousture..

A mouse gesture library written soley in javascript with power and flexiblity to mould itself for you. Implemented on Mootools following the Object Oriented standards. Library is aimed to set out a future framework for mouse guesters for any browser including modern mobile devices.

Its based on simplicity. Three major concepts.
A probe, which probes the pointing device. Currently there is a Moousture.MouseProbe (P.S. It already supports iPhone).
A monitor, which tests the stability of probed device on given intervals and accordingly notifies Moousture events (onStable, onUnstable, onMove).
A Moousture recorder class that records the mouse movements and invoke the guesture object passed to it.

its quite awesome and very nice idea for downloading images files etc , david walshi did a quick demo and there is couple of more demos on her website, links below
