specifically, I do not know of a website that has done it, and I sure havent tried. Your quesiton is a little broad and general. I'm not sure exactly what to tell you. But I can't just make something for you. I would try and learn a little more about MovieClips, and attaching MovieClips with actionscript. This might give you a better idea of what you want to accomplish other than "make a sprinkler"... If you want my advice. Try and make a MovieClip that attaches another MC of water over and over. Then try and make it spurt from that MC into different directions with different _x and _y speeds. It would take a little trying it out to get it right. But learn a little more to try and understand what you are creating before creating it.

Hope I could help!
