It's always fun to see the crazy things our geeky brethren are able to create with some sensors and a Wi-Fi connection, but unless you've got plenty of time and a penchant for coding, odds are those projects are out of reach. That's where Twine ($100 and up) comes in. Twine is a wi-fi- and sensor-laden gadget that hooks up with a web service to monitor whatever you want in real-time, updating a dedicated Twitter account when necessary. Sensors residing inside the 2.5-inch, soap-like square include a thermometer and accelerometer, and you can add external sensors with ease. Just don't forget to follow your own Twine, lest your warnings of a freezing house go unnoticed.
