Thank you so much, your comments really made my day!

I played the wind farm in Oct-Nov of last year on my old computer (now deceased) that was 6 years old, 4GB RAM and a mid-range video card, and it lagged just a little when I first opened the lot. After that I didn't notice any lag. Perhaps the solar panels would be a better choice since they have no moving parts.

I get a lot of inspiration watching other people's challenges too!

I hope to have Jill Fleig in my BaCC one of these days.
