Actually he's got an advantage. Light has no mass (not going to split very very fine theoretical hairs here), but sound transducers and laser scanners do. By understanding bandwidth limitation, time domain filters, slew rates, wavefront and phase distortion, resonance, a sound engineer has quite the head start on understanding scanners, scan amps, dichros, lasers...
EDIT: While that big logo will flicker, that could be a virtue if you like the effect once it's set to pick out letters in an entertaining order. It may well look interesting if you don't try to pick them out in the actual written order. Also, flicker is based on persistence of vision, and as this is party a brain thing, it may be that by multiplexing the letters this way, the perceived flicker may be reduced anyway. Don't quote me on this because I'm not sure of it, but it's worth testing.
Also, never mind mixing letter order, why not mix stroke order? If you can draw strokes of three letters one in each line by barely changing direction that is fastest. Routing it all would be tough, but an interesting and maybe rewarding puzzle.
