Countdown Challenge

Like what?

This one took over a year to finish.

I guess it's all done. This thread started on 9-29-2006, so it took 1 year, 2 months, and 3 days to complete.

How about 20k? Increase it by 10k or we can start a new thread and do it and stop this on we can make it Countdown Challenge 2

Well this one started at 10,000 so maybe double it? Or 25,000?

Looks like 20K it is! I'll get it started!
