Rendered out my first fluid sim in Realflow and Cycles 4d. It's not perfect but I found the overall usage of Realflow straightforward. I'll have to try and do this with xparticles too. You can find the animation here: Life is sweet.
I'm new to c4d, just added it to my 3d tools (modo and zbrush) Playing with c4d is fun. Displace a plane, clone an eyeball, tag dynamic body add random to taste. You can see the result here.
