Your laptop could help detect earthquakes

RantWoman cannot decide whether the following item is really cool or another freaky instance of our devices getting too smart for our own good.

This item is about an application using the accelerometers built into new laptop computers to detect tremors, ping a host, and, if enough other computers in the same area also ping a host server to general warnings of earthquakes, hopefully at least sometimes in time for people to move to safer locations.

The actual Quake catcher link with its downloadable client is here:

RantWoman is posting the link in hopes that some of her alert readers will try it and join the network. RantWoman supposes, given her own needs and the demographic she is feeding info to, some comments about accessibility would be fabulous as well. RantWoman is getting ahead of herself. Comments welcome.
