Feel free to dig into this old project I did for TD 77 with Cinder circa 2012/2013
I implemented Hai's FluidFX as a CPP Top. It worked great for what I needed, but I didn't get Graphics.cpp working because I didn't need it at the time, but it would be awesome. I have been meaning to get around to updating it to Touch 99 and the Cinder master branch, as there's been a few requests.
What I would really love is if Derivative opened up the SOP (Surface Operator) API so you could write a CPP SOP. I've pinged Marcus at Derivative about that back in the day, but I haven't heard of plans to make the API available.
