Nick obviously wants to learn something. Nigel thinks that really sucks because the wheel HAS been invented zillions of years ago, so why discuss wheels anyway?

If history would have to rely on Nigels, we would probably still live in caves, eat bears, wear beavers (or the other way around) and drive on horse-pulled carts with wooden wheels and stone suspension (or the other way around).

This ugly statement probably requires me to give some relevant answer as well. So I would suggest to take a look at this link first (it's Dutch, but so am I; luckily, the contents of the page is in English)
