At the no longer very recent NCAD Graduate Show, it was Ronan Horan's work in the Visual Communication show that most impressed me. Horan noted that as our modes of communication are changing, and indeed shortening, the way we use language needs to change also. Already we've developed text chat as a modern shorthand, but that's rotten looking, so Horan's designed some ligatures to join the ampersand and make abbreviated type a lot more attractive. They're elegant, but more importantly quite easy to understand, making you wonder why nobody came up with them before.
