### Description

The $D^3$ project has been investigating gas Time Projection Chambers with charge readout via pixel chips, a candidate technology for future directional Dark Matter searches. We have constructed a number of small prototypes over several years, and are now at a stage where the detectors operate stably over long time scales, and the 3-D ionization distribution from nuclear recoils can be imaged in detail. This enables new background rejection techniques, such as obtaining the absolute position of nuclear recoils from the transverse diffusion of the ionization cloud. I will review the most interesting results to date, and comment on the feasibility of constructing much larger, future detectors, with the ultimate goal of probing WIMP-nucleon cross-sections below the neutrino floor.
