Jonathan Nathan today announced the availability of Lilt 1.0, a unique tool for Mac OS X and Macintosh systems that feature light and/or sudden motion sensors. Lilt utilizes the ambient light and sudden motion sensors found on recent Mac portable systems to trigger actions such as launching applications, files, or scripts. “Wave your hand over the light sensors (located under the speaker grills) and play your next iTunes track. Tilt the computer back and put your machine to sleep. The possibilities are endless.” Lilt requires Mac OS X 10.4 or later and is priced at US$5.
