Quote: Getting a bit more complicated (as brain storming sessions are want to do ) but a digit setting circle with an LCD readout that could be placed where the use would like it. But nixie lights would be uber cool.
Oh yeah, those nixie tubes are sweet! And a HALO all tricked-out like that would definitely have a very cool "retro-modern" look to it! Not sure anybody would buy a HALO made that way, but it would sure make a nice conversation piece.
