Whether you’re just rearranging the furniture or doing a full-blown redesign, PlanningWiz makes it easy and fun. This is a fast-loading Flash application – so there’s nothing to download – and you can save your designs by creating a free account. (Sign-up was approximately 10 seconds – couldn’t be easier.) It comes with a pile of pre-sets, including tons of templates for couches, beds, TVs, dressers – you name it. So be adventurous – it’s a lot easier on your back than experimenting with the real stuff! Click here to check out PlanningWiz v3.
