Okay, its over. It was actually quite fun, especially since I wrote a GUI and could see my car racing around the tracks.
I spend 10am Saturday to 3am Sunday morning (Australian EST, GMT+1000) working on my "lightning" entry (the first 24 hours constitutes a "lightning" division). I then spent about 7 hours on Sunday rounding out my main entry.
I am putting together a permanent record of my efforts.
