The Wide-field Infrared Survey Explorer (WISE) surveyed the entire sky in four mid-infrared bands, at 3.4, 4.6, 12, and 22 microns during its 8 month cryogenic mission. The number of independent WISE measurements of a source is a function of its ecliptic latitude. Sources near the ecliptic poles can have hundreds of measurements while sources near the ecliptic plane tend to have as few as eight observations due to the ecliptic polar orbit of the spacecraft. Therefore, the vast majority of detected variable sources and flux transients occur near the ecliptic poles. We present some early results of variable and transient searches in the WISE preliminary data, including light curves of new pulsating and eclipsing stars, as well as peculiar QSO sources. We also detail the selection method used in this project and the the plans for a WISE variable source catalog using the entire mission data.
