There is a new iOS app called Vent devoted to letting people complain about their lives. It's a shitstorm in the making.

File these under "new to me" category, but while I'd seen programmable thermostats before, I'd never encountered a vent that opened and closed on a timer.

After some users discovered that the back vent in some MacBooks were blocked by plastic, and then subsequently blogged about it, Apple's released a somewhat official statement about the matter through their Support Site.
