Shoes that Tweet?!?!?

Ricardo Nascimento has created a pair of shoes that tweet as you walk! A sensor placed inside the sneakers track your moves and updates it on your twitter account! There's not too much information out there yet about these "tweeting shoes" but it seems like they don't have that much of a vocabulary :)
Personally I don't use twitter so these shoes are a no go for me, I'll stick to my heels!
