Everyone's an inventor at heart, but don't you just hate it when you see YOUR idea in production, and some other stiff making money out of it??? I remember when I was 14 my brother and I used to design cars, and were also interested in planes. I came up with the idea of a powered luggage car that also doubled as a set of stairs to the plane doors. I've no idea if they were around at the time, though I doubt it, but I've seen heaps of them at airports since! So, true stories only, dear Netriders, what did YOU think of first, before some other lucky mongrel got rich on it???
