Saison fermentation. White residue and thin film. Infected?

I'm ferementing a saison with Wyeast 3724, and after the initial ferment, it died down, I then bought it into a warmer room and chucked some blankets over it (I'm also using an aquarium heater, but that alone wasn't working). I checked on it last night, and it seems to have fleks of white on top, as well as a thin film. The smell is also rather funky (I guess this is usual for a Saison). Here's what it looks like:

Is this usual for a saison, or have I got an infection on my hands?

Sorry to say that looks like the beginning of a pellicle, meaning your beer is infected. But if you drink it quickly, you may avoid the worst of it. Best case, it might even taste good! And NEVER put that heater in your beer! Put the beer in a tub of water and put the heater in the water.
