the round orange saviour
Now I like the look of this. The astonished gazes of onlookers, as you momentarily roll unbruised away from the scene of a nasty pounding by a big, stupid van driver scanning the map on his clipboard to see the next perfect geographical position in which he (or she- mustn't be sexist) can display their total ignorance of road manners, safety and craft, only to carry on rolling away from the scene over the nearest available precipice.
How about designing it to inflate into a cuboid? Something that will stop rolling reasonably quickly, and be entertaining into the bargain. Onlookers could then amuse themselves by trying to guess what number we'll land on.
Then there's the issue of vomit. As we're reeling away from the scene, dizzy with joy and just plain dizziness, vomiting wildly, to reassure our brains that that particular function is working as it should be, we realise that the globe is orange on the outside and we've become moistly orange on the inside.
This brings me to air. Will we emerge from this ballooon realising that we haven't just emerged from the ballon, but actually merely dreamt about emerging, as we've just asphyxiated in a lack of oxygen and an abundance of stomach contents.
Now if the designer solves these little issues it will probably become to expensive for you or I to afford.
But rest assured, all our favourite celebrities - footballers, overpaid X-factor runners-up - will be able to. That's the important thing.
