FINAL THOUGHTS
If I were to do this again, I would utilize the same concept perhaps but maybe spell out the word KABOOM in red LEDs and shape the sliding panel switch like the push down bicycle pump-like handle for explosives you see in old Bugs Bunny cartoons or perhaps make a box with a switch that when flicked on will flash USA USA in red white and blue LEDs. I could bring this to a sporting event and hold it aloft and amaze everyone and get on ESPN.
