The PopSci staff has been darting all over the country this week--Las Vegas, Detroit...I guess that's it, but still, those are two places more than we usually go. And at those conventions, surrounded by tens of thousands of people, we often get to wishing we were undetectable, able to drift through the crowds silently and unseen, snapping our photos and then getting the hell out of there. This week's roundup illustration speaks to us.
Want to win this sneaky Baarbarian illustration on a T-shirt? It's easy! The rules: Follow us on Twitter (we're @PopSci) and retweet our This Week in the Future tweet. One of those lucky retweeters will be chosen to receive a custom T-shirt with this week's Baarbarian illustration on it, thus making the winner the envy of their friends, coworkers and everyone else with eyes. (Those who would rather not leave things to chance and just pony up some cash for the t-shirt can do that here.) The stories pictured herein:
