Having fun with a colour led stick behind my moving wife holding a different pause the time I "paint" behind her to reveal silhouettes of her in front of differrent rainbow colors on a boat dock to get reflections in the water. A few days before, i went alone to do some testing....after midnight...then colorful flashing red and blue lights arrived in the parking! Did a demo for the officier...and I did "pass go, collected $200, and didn't go to jail"!
