I have an openclaw install on an old Mac Mini and realized i wasn't using the audio out, so I ran it through a Macrosilicon capture card into a Hitachi V-1100A oscilloscope (100MHz, circa 1983 i think?) and told Claude to emit different sounds based on what actions it was taking.
Kind of dumb, but pretty fun.
