Color Code Your Keys. Could be a quick an easy craft on the days we need something quick -- could have people know before hand to bring their keys if they wanted. but then again people might not want to color code their keys?
This is a design by: Andre Rumann. It is a simple little product that involves a keychain holder (being the garage) and a keychain in the shape of little mini car. So when you return from work, simply park the car (and your key) in the garage :)
