Ask HN: Learning FPGA's as a Software Developer?

I have a few cool projects in mind that would have me building some prototype hardware. As this hardware would probably go beyond what you could do with say an Arduino or similar MCU based board, and I'm not an hardware engineer, it seems like FPGAs or some other form of programmable logic is probably my best bet.

But most FPGA material seems to be for EE's. The HDLs seem foreign and there are so many brands, options, etc. It all seems so intimidating.

Are there any recommended resources for learning FPGA's coming from a software background?
