We present work towards a new direction-sensitive WIMP Dark Matter search experiment. The Directional Dark Matter Detector (D^3) will search for WIMP-induced nuclear recoils in gas-filled Time Projection Chambers (TPCs). By reading out the TPC drift charge with Gas Electron Multipliers (GEMs) and pixel electronics, the primary ionization in the target gas is detected with low noise, good position and time resolution, and high efficiency. These features may allow Dark Matter searches with improved sensitivity, particularly for low-mass WIMP candidates. We will review past experimental results, ongoing construction of second- generation prototypes, and speculate on the prospects of using our detector concept to build a large scale cost-effective experiment. We will also comment briefly on other possible applications of TPCs with GEMs and pixel electronics.
