Electronics retail chain Radio Shack, online collaborative Quirky and Austin-based, Omnicom-owned GSD&M have teamed up to extend the brand’s “Do It Together” mission by launching an invention challenge for kids and budding inventors. The Shack is inviting its target audience to contribute “smart” toy ideas with the opportunity for the best one to become a sellable product on the chain’s shelves. It doesn’t look like there’s much time (well, seriously, there isn’t much time), but you can check out the site here to submit your concepts, which will be judged live on June 5 at Quirky.com. This effort marks the latest partnership between Radio Shack and GSD&M, which began working with the brand last year and created their well-received, 80’s-loving Super Bowl spot. And if you can bear the crap weather here today in NYC, tonight, the brand and Quirky are hosting a Sketch and Design night at the Radio Shack Concept store on 150 E. 42nd St. from 4-7. Enjoy, kids.
