Here are the previous (newly finished) panels 3 & 4 with their brethren 1 & 2, all in sparkle mode. I also demonstrate how flexible each LED panel is, they are pretty resilient! The sparkling effect is created when the 555 timer is in scanning mode, but the clock line is left to float near-but-not-touching so the panels are susceptible to outside EMF for timing (too fast to light up), but have an influence by the 555 (a momentary pause of light; the sparkle).
