Taking on a build-a-day challenge is not for the faint-hearted. I could never do this, not without some sort of benefactor sponsorship and a lot of help with all the other tasks of running BrickNerd. But builders marcu44 and 'rolli are just crazy (crazy talented) enough to take this challenge on. Last month marcu44 succeeded in rolling out 27 awesome MOCs based on Harry Potter and the Philosopher's Stone (which I failed to cover, I have no excuse) and this month his friend 'rolli is attempting a build a day for Harry Potter and the Chamber of Secrets. The effort, detail and caliber of all these MOCs can be described as nothing less than magical. The question is, who is going to step up for Prisoner of Azkaban, are you up to the challenge?
