Is this what my primary fermentation should look like after a day??? It looks like my yeast has been sitting on top of foam..

That looks like yeast that is sitting on top of a foam (krausen) that was produced by more yeast. I assume you poured dry yeast directly into the fermenter? All it means is that some of it clumped up top instead of sinking down. The rest took over quickly and have been happily munching away. A worst case scenario is the yeast was old and some of it had died. This would have a greater potential to produce off flavors. If you didn't have foam, you would probably want to re-pitch. As it is, relax, don't worry, have a homebrew.
If you want to avoid this from happening in the future, make a starter the day or two before and double check the date on the yeast package.
