CS-oriented Ice-Breaker Games I will have my new incoming CS freshmen (HS) for a week-long summer orientation in August. The kids don't know each other yet, so Ice Breakers are in order! Has anyone encountered fun, physical CS-themed games for helping kids to loosen up and get to know one another?

Criteria: the students are not required to come in with any background, though they will be learning some very basic programming concepts over the course of the week that we see them.  Ideal games would either directly expose kids (in a non-technical way) to CS concepts, or could be referenced later (days, weeks, months, or years) in lessons to help explain concepts down the line.

Answers where you have direct experience with the game (and can vouch that it is fun!) are doubly appreciated.
Get them to line up (preferably on a wooden gym bench), then get then ask them to get into alphabetical order. You can use this to help learn names, and to introduce sorting algorithms. 

I could also recommend CS-unplugged, it is part of the computational thinking, so aimed at very young pupils (primary school &lt; age 11years old), but can also be used with older students.
