Excelcius Hi there is an shake event class written by Shilo which is compatible with Sparrow 1.x not sure about 2.0 and above, but you could download it and give it a try, or at least examining the source code could give you some pointers as to how to implement it http://wiki.sparrow-framework.org/users/shilo/extensions/shshakeevent I haven't tried it myself so if anyone else knows why it might not work with Sparrow 2.0 and above and if you have to implement it differently in 2.0 and above please chime in.
Shilo Excelcius, thanks for the answer. Jbernabeu, I created a new version for you: SHShakeEvent for 2.X As Excelcius mentioned, you can also dig through the source and implement your own solution that doesn't depend on SPEvent.
