The Machinery's Machinery

I mentioned yesterday that this piece was somehow done with the variable width tool in Illustrator again. Here's a peek at how that happened and a look at how powerful it can be to get your bezier handles parallel.

With a script like this at least, all the handles, with the exception of end points (and the occasional supporting points in the middle of a "S" curve like the swash on the 'l' in 'always', for example), should really be either parallel to each other, or occasionally perpendicular.

Of course there are sporadic exceptions to this, as there are with any rule—but not many.

There's a bigger shot attached for a closer look.
