Wahoo! At my current pace I will pass the 100,000,000 (one hundred million) structures mark sometime tonight or tomorrow. I'd like to thank the following people for helping me reach this achievement:

The designers of the current DF engine.
I'm also active on Folding@Home, but I can't devote my full 77GHz of Pentium 3 and 43GHz of Pentium 4 computing power to their project because it requires constant interaction with the Internet. My folding boxes are set-up on a private test network that is prohibited from touching the Internet.

His dfQ project gathers the work done by all of my DF client boxes so that it can be uploaded efficiently and automatically. It was taking me about an hour per day to do the same job manually with the clumsy batch files I wrote to gather DF work and I was also losing work to a timing bug that I never quite got fixed. M0ti's dfQ stuff just plain works for me.
