Started a brew

So I got started on my Pumpkin Cranberry Sour ale over the weekend, I started the funky beer that I will be blending with my fruit beer for the finished sour product.  You can see the recipe I worked out here, as for the beer I'm trying to clone you can find out about that here.  I need to get a picture of this beer, the combo of the Trappist High Gravity yeast and the Lambic Blend has the largest krausen I've ever had.  It's only 4 maybe 4.5 gallons in my 5 gallon carboy and it's trying to bubble out the airlock!
