I'm continuing to focus on the national academies, NSA and DARPA as sources of funds to local area NGOs, as well as private trusts (fund accounting management tracks by donor, with those wishing anonymity to retain it to some degree -- as long as we have ample transparency).
Saturday Academy received a large grant from Paul Allen recently. Python was already a recipient of DARPA funding.
The NSF has funded a lot of dubious projects, plus turned down the promising First Person Physics I was involved with, out of University of Nebraska (Bob had all his ducks in a row, the peer reviews were mostly positive).
Engineers at NAE have proved far more receptive to the Fuller School than have the NSF bureaucrats.
The Department of Education has also proved itself entirely irrelevant to my projects (right up there with the NCTM in terms of making no positive difference in our living standards).
Anyway, there's a lot more about this stuff in my blogs. Math Forum is not a place where I go into any details regarding my funding sources.
