  We prove existence and uniqueness for a two-parameter family of translators
for mean curvature flow. We get additional examples by taking limits at the
boundary of the parameter space. Some of the translators resemble well-known
minimal surfaces (Scherk's doubly periodic minimal surfaces, helicoids), but
others have no minimal surface analogs. A one-parameter subfamily of the
examples (the pitchforks) have finite topology and quadratic area growth, and
thus might arise as blowups at singularities of initially smooth, closed
surfaces flowing by mean curvature flow.
