Not hardware, but the old polygon rotation code I made in Lua to generate wave data can be ported to C and Win32 API, to use the MIDI and audio handling code I already made for my phase mod synth. It does logarithmic maths for speed. Small ILDA sequences may form raw data for rotation, allowing for some interesting hybrid abstracts. My emphasis was always on high precision on a wide range of visible scale, rather than raw speed. These galvos might allow this in ways the Widemoves failed to do.
