I saw this on the cover of Popular Science the other day. It's an electric unicycle (yup, unicycle). My brother and I had a unicycle when we were kids, and it was the most horrendous thing to ride (the tiny, uncomfortable seat was the worst part). At least this thing has two central wheels and handlebars. The intent is to produce a highly efficient personal vehicle that doesn't pollute. It's probably not as dangerous as it might seem, since it uses the same sort of principles as the Segway to achieve balance. It was invented by an 18 year-old in Canada, so this is another thing to blame on Canadians ;-)

The image above is my interpretation. The prototype has an orange body (which is probably good since it would be easier to see in traffic).
