The other idea that I'd had, with having sensors like this attached to the internet, was an early warning system that's cheap to deploy everywhere and effective.

I'd asked myself this question, back in march.

"How THE HELL - in 1967 - do you design something so good, that: after lasting 10 years beyond your intended design life - can also withstand a quake 7x the size of what you designed it for? Followed by a tsunami? Whose hand can I shake? Who gets a medal? Are any of those engineers from the 60s still alive? I mean, WOW. They did that design, at least in part, with slide rules."

It's really amazing what watching some jugglers equipped with ardinos and accelerometers can do to your thinking, especially if they are speaking in a language you don't understand, but show off the simplicity of the gerbers and chipset 4 minutes in. Gerbers are a language I do sort of understand.

There's all kinds of artistic things the demoscene is doing with this now incredibly cheap stuff

Seismograph is a possibly practical application. + Perfect time, perfect location and altitude lock. Don't know if 12 bits at the sample rate is useful tho. One indirect measurement is the effect on the network of earthquakes.

Sparkfun also has various accelerometers on breakoutboards (and others including a board that has a gyro and compass too).

The Skytraq also has I2c (I was originally trying to use it to pull J1850 data instead of my latest solution)

Dave suggested using it as an el-cheapo seismograph in areas with poor coverage (which doesn't describe here, but apparently does describe a lot of central America).
