18 pages - There is a serious mistake in the proofs of Lemma 2.3 and Theorem 2.1 and also a mistake in the proof of Lemma 4.5. These mistakes have been pointed out to me by Rene Ruhr to whom I am now greatly indebted

In this paper we study the set of values of quadratic form at points of a cut and project set. We will establish conditions which ensure that the set of values is dense. Our methods involve homogeneous dynamics and we will prove a orbit closure classification type result in this setting. This result has additional applications. In particular, we use it to study the set of integral values of a system consisting of a quadratic form and several linear forms.
