1. A flexible skateboard, comprising:
a one piece molded plastic platform twistable about a twist axis, the one piece platform molded to comprise
(i) a pair of foot support areas along the twist axis, generally at each end of the platform, to support a user's feet,
(ii) a hollow wedge molded into each foot support area, and
(iii) a central section molded in between the foot support areas; and
a pair of caster assemblies, each having a single caster wheel mounted for rolling rotation, each caster assembly mounted to one of the hollow wedges, for steering rotation about one of a pair of generally parallel pivot axes each forming a first acute angle with the twist axis;
wherein the central section is configured to be sufficiently narrower than the foot support areas to permit the user to twist the platform alternately in a first direction and then in a second direction to add energy to the rolling rotation of the caster wheels.
