Core77 just announced their latest One Hour Design Challenge, and this time there’s a Nintendo Wii up for grabs. So, what does one have to do to score the system that makes champions of both rockstars and losers alike, you may ask? Bust out your tablet, skip lunch and design a water-saving plan for a bathroom. Not toooo shabby for an hour’s work…unless you’re an illustrationally-challenged lifeform, or would just rather stand in your shower, soaping up your althlete’s foot. To get in on the action — you have until Monday — click here, and to see the entries to date, visit Core77’s forum here.
