We're giving away a popular motion loop

You can't have enough motion loops... that's what my parents always said to me as a youngster... okay, maybe not that, but they taught me to say 'yes sir' and 'yes maam' when speaking with adults.  It's just polite to use those terms... I'm still trying to teach my daughter not to ask our dinner guests to leave... while we are eating dinner.  What was this blog post about?
