Abstract: Time permitting I shall get around to talking about three interrelated topics on perimeter generating functions for convex polygons.

1) Directed column-convex polygons and hypergeometric solutions to the cubic equation.

2) Some new types of column-convex polygons.

3) Enumerations on the square lattice by perimeter and right-angle bends and how this leads to perimeter generating functions on the (4.8\(^2)\)-lattice.
