Someone already wrote a short text on the Lotus effect, but I just found this video on ABC which gives a good explanation also about the process of mimicry of this effect.

I also heard that the car and motorcycle brand BMW looked at this affect. In a paper about motorcycle technology they talk about nature as their role model. Three examples are shown: The fir cone principle, the lotus effect and the spider's web. These 3 inspired different technolgies as you can read on the following page.
Whoever wants to read a little more into the paper, just follow this link which goes deeper into the technologies applied to motorcycle suits.
