Spherize

The Spherize filter wraps a clip around a spherical shape, and is useful for giving objects and text a three-dimensional effect. You can set the intensity (amount) from -100 (a concave appearance) to 100 (a convex appearance). You can also select the direction in which the effect is applied: Horizontal Only, Vertical Only, or Normal (in all directions).
