The mysterious nature of dark matter has eluded explanation for decades, and remains a major puzzle in physics today. Detectors that search for the direct interaction of dark matter with target nuclei must distinguish rare dark matter interactions from abundant backgrounds that can masquerade as signal. Searches for dark matter have not yet fully exploited a unique astrophysical signature of dark matter: the angular distribution on the sky. No known background can mimic this expected forward-backward asymmetry of WIMP-induced interactions. I will give an overview of directional dark matter detection, and describe recent results from the Dark Matter Time Projection Chamber collaboration.
