Cygnus X-3 is a very bright and unusual X-ray source. It is a high mass x-ray binary that has been studied for over 40 years. However, it wasn't until the birth of Chandra that we could take full advantage of the information provided by this unique object. In 2006, HETG/ACIS observations of Cygnus X-3 were taken during a high state. Where as some sources struggle to get hundreds of counts, in the first order of these grating observations there were over 7 million events. The richness of this spectrum allows us to try things that have not generally been done with x-ray spectra. Specifically, we have created several dynamic spectra allowing us to explore line variations in both phase and time. These dynamic spectra show that some of these lines vary both in strength and wavelength as a function of phase. We also explore the applicability of doppler tomography to Cygnus X-3. While we are only dealing with resolution around 100 km/s, this allows us to examine different emission regions within the strong wind associated with this system. Initial results are previewed and the potential knowledge that can be gleaned from this technique will be discussed.
