Yeah, or like one of those pulsating shower heads. I wonder how those things work??? From the article, it sounds like the frequency of pulsation needs to be pretty quick and I'm not sure you could ever get a shower head type of system to pulse that fast. The only other option I could think of would involve a spinning disk with holes or slots in it....or maybe a spinning ball valve. I'm not fond of either of those solutions, since they probably won't be very reliable due to the fast moving parts. That also makes it pretty expensive.
