What does it take?

What does it take to make this:http://home.wanadoo.nl/~mjhoeve/HMSim.swf.

I've always wanted to make one like this or at least play one but I want a more complex ride (like Mondial Revolution [:p]).

I get a broken link.

That's the good one...

Well, the time does matter hot experienced you are with flash and how complex this is. I have a very little experience with flash so i only can say it will take a very long time to get this done...
