Typical, I go away for a while and completely miss another competition.. There was a breakfast machine in Back to the Future (the first one and Doc's absence made it a terrible failure in the movie) and I'm sure Wallace & Gromit had one too.
Mine would have been the bluetooth earphones Ryan Renolds has in 'Definately, Maybe'. They're wireless and tiny and I've been wanting to try to make some for a while now, but I don't think the tech actually exists, batteris being the biggest problem so far:
Or I'd like some sort of automated indicator for cars/motorcycles for when all those brilliant people on the road can't move their finger's a couple of inches to let other people on the road know what they're going to do and waste my time sitting there waiting for them to drive past my junction, only to turn before they get there. Or even better yet, a huge arrow on top of the roof of the vehicle (not sure where it would go on bikes) that points to where they're going, that way when you can't see their indicators or side repeaters because of the angle, you can still see if they intend to change lanes into the space you occupy, exit a roundabout or turn into another junction.
Not to forget giant, transparent screens/windows. So the dark centre of the office/fishbowl that I work in could have the glass we're surrounded by display something more interesting than a dark, empty office. We could have a tropical beach, space filled with stars or even an intergalactic planet, just to liven us up a bit and make us more productive.
