Frankly, first I need to find a saw that isn't blunt.

(Actually, finding any kind of tool isn't easy. My mum *has* millions of 
tools - every time she goes to start another job, she can never find the 
tool she wants, so she buys a new one. It gets used once, and is never 
found again.)

I said "chance". :-P

Actually... it's possibly not directly related, but Wolfram showed a 
trivially simple cellular automaton which has no sophisticated 
properties encoded into it, and isn't even an accurate simulation of any 
physical system, and yet exhibits the same characteristics as a flowing 
liquid. (Most particularly, it has both laminar and turbulent flow.)

This is much simpler to model then exotic differential equations. OTOH, 
it's a few orders of magnitude less efficient too... ;-)
