Game Changing: The Node Power Outlet
Prepare yourself to quietly think: "How come I never thought of that?". The Node Power Outlet solves the problem of not having enough outlets and/or not wanting an ugly power strip laying on the floor. The two grooves curving around the wall plate are available to plug in whatever you got, making this the kind of thing that should start coming standard in every single home.
Right now, the Note Power Outlet is only available in Japan but you can order online if you're able to read enough Japanese (or patiently use Google Translate) to guide your way through this e-commerce store.
