We propose a renormalizable model with no fundamental scalars which breaks itself in the manner of a tumbling'' gauge theory down to the standard model with a top-quark condensate. Because of anomaly cancellation requirements, this model contains two color-sextet fermions (quixes), which are vectorlike with respect to the standard-model gauge group. The model also has a large number of pseudo Nambu-Goldstone bosons, some of which can be light. The top-quark condensate is responsible for breaking the electroweak gauge symmetry and gives the top quark a large mass. We discuss the qualitative features and instructive shortcomings of the model in its present form. We also show that this model can be naturally embedded into an aesthetically pleasing model in which the standard-model fermion families appear symmetrically.
