I just experienced a Sunday evening epiphany, straight from the garage after spending several hours building my back panel for my projector case:
* My first EVER live laser show was put on by a band called Electric Light Orchestra, who commonly went by the acronym ELO.
* My first touch-screen monitor purchased so I can perform live laser shows is produced by a company called ELO.
Whoa ! 
No alcohol was involved during the journey towards this epiphany - at least, not today.....
