I like the point distance being 0.2. You get more straight lines in them ... great for railroads. The tracks still follow the general trajectory you want (the terrain?), and pass through the cities (the 0.5 points!), but you get more straight track runs. Straight tracks can be safely traversed at higher speed. :) Also nice for garden paths where a balance between alternating curves and straights is more interesting. Fun tutorial! I also have a bezier library I wrote but had not heard of the Chaikin version.
