We present a preliminary analysis of the cool pulsating white dwarf GD~1212, GD\,1212,  enabled by more than 11.5 days of space-based photometry obtained during an engineering test of the extended {\em Kepler} mission in 2014 January and February. ({\em K2}).  We detect at least 21 independent pulsation modes, ranging from $369.8-1220.8$\,s, and at least 17 nonlinear combination frequencies of those independent pulsations. Our longest uninterrupted light curve, 9.0 days in length, evidences coherent difference frequencies at periods inaccessible from the ground, up to 14.5\,hr.  ... More abstract will come here ... 14.5\,hr, the longest-period signals ever detected in a pulsating white dwarf.  These results mark some of the first science to come from {\em K2}, proving the capability for unprecedented discoveries afforded by extending {\em Kepler} observations to the ecliptic.
