Joe Harrison has a pretty brilliant idea that makes me think, "why haven't we thought of this sooner?". He has started two projects, Responsive Logos and Responsive Icons. Both "explore scalable iconography and plays with the varying complexity of symbols on devices, aiming to find that perfect balance of simplicity in relation to screen size", says Joe. He states the projects are in their early stages, but you should check them out regardless. Although most designers might cringe when thinking about having to create even more versions of logos, this seems like a no brainer for the future. Keep it up Joe.
