Track the touch input of your Mac Multitouch Trackpad
If you’ve ever wondered what your Mac Multitouch Trackpad is doing, download this fun little application. It tracks multitouch input and shows you just how sensitive the multitouch surface really is, detecting up to 11 input points, and also knowing the surface area. Not the most useful app in the world it’s certainly a fun way to see what your multitouch is up to and to get a glimpse of the technology behind the scenes of our favorite laptop computing surface. Multitouch trackpad Mac required (works with the Magic Mouse too apparently), and this supposedly works on some 2008 MacBook/Air/Pro models as well but I’m not able to test them specifically.
