We focus on noncommutative Lorentz transformations. We then discuss the structure of the light cone on a canonical noncommutative spacetime and show that field theories formulated on these spaces do not violate mircocausality.6 pages, to appear in the proceedings of 40th Rencontres de Moriond, Electroweak Interactions and Unified Theories, March 11 - 18, 2006; v2: minor typos corrected, one reference addedHigh Energy Physics - TheoryHigh Energy Physics - PhenomenologyMathematical Physicstext
