Have you ever thought that everyday activities like, say, summoning your family for dinner, need a little more drama? Bttn, a giant, shouty, Wi-Fi-enabled button, is thinking yes.
Bttn's premise is very simple: you push the button (I mean, what else are you going to do with it?), and it sends a signal to a server (via Wi-Fi or a cell network), which then carries out a pre-programmed action, be that turning on your Wi-Fi enabled lights, or sending a text to your children telling them to get their asses home right the hell now. The list of actions is pretty unlimited: bttn plugs into IFTTT and a couple other services, and thereby into almost every social network or other internet-connected thing you can think of.
If you're interested, the IndieGoGo campaign will let you pre-order your choice of red, blue, green, or yellow bttn for a pretty steep $99, with delivery promised (although you'll want to take that with a prescription dose of scepticism) by Christmas. [IndieGoGo]
