About what 99% of the pics in the "is my beer infected" threads actually turn out to be when we look at them.
Yeast colonies on top of a beer are so common that they have the nickname "yeast rafts." They are buoyed to the surface due to rising co2 being released from the trub, not just due to fermentation, but also changes in temp or atmospheric temperature.
Very rarely is the surface of a beer totally free of something floating on it.
