Any other isf shaders out there?

I really like the idea of ISF shaders, and about 5 of them seem to be decent.

however the only resource I can find is the ISF shaders sharing community place, which has the same ones, no new ones seem to appear.

It seems like not much of a community around this sort of thing. Is there anywhere where one might obtain high quality ISF shaders/filters/and generators besides the free resource?

I would pay money to have super cool moving graphics (generators) and psychedelic style (filter) shaders. Is there something im missing, or another way to do this?
