The pseudo-code contained an alarming number of bugs (one of the nastier ones is depicted above), which made it difficult to implement. Readers pointed out these in the comments, and so [...]

This tutorial provides some algorithms useful for working with Bézier curves: determining the length of a piece of curve; interpolating a set of points with a Bézier path; and reducing a large point set to a smooth Bézier curve.

A distillation of the five puzzle game design interviews, taking together advice from Rob Jagnow, Guy Lima, Ted Lauterbach, Teddy Lee, Dave Hall and Teddy Lee.
