Vase-O-Matic!!!

Parametric vase / pencil cup / objet d'art generator. Use small sizes for the square and large radii for rounder objects; use larger squares and smaller radii to produce objects with a more square form. Base form can be twisted clockwise, counter-clockwise, or both. Base form can also be flared or tapered to make interesting shapes. Adjust the floor thickness to make shallower / solid / bottomless objects.
