Clouds in higher dimensions

Abstract
Subsets of the plane called clouds have been studied by Komjath and Schmerl, who have shown that the number of clouds needed to cover the plane is related to the cardinality of the continuum. We will prove that their results extend to higher-dimensional Euclidean space; this will include revisiting Schmerl's proof and seeing that it extends seamlessly to higher dimensions.
