Amazing topic! Gives me some quality associations on human behaviour that is better I don't say not to offend anyone. I remember one superb video, a guy poured alloy in ants construction within soil. Unfortunately, he destroyed many ants, but the metal outflow was absolutely perfectly shaped and complex. I couldn't believe my eyes. I was totally amused seeing it. Try to google it under video section, I seen it in documentary but maybe you'll get lucky and that would be perfect include to your post. Well done! Absolutely interesting. reestemed!
