This is an impressive project, but it uses an FPGA which is completely unnecessary. With modern processors there's no reason you can't do all the requisite computations in software, provided you use realtime programming techniques. I know this because I built a laser vector projector in the 80s driven by 8-bit processors of that era. It didn't use SVG as input; that definitely needs more cycles, but with a modern processor it should be easy. Galvo motors are S-L-O-W compared to CPUs.
