Blinking Dot Sync

I noticed tiny red and amber sparks flickering beneath the television. Step one: navigate the dark wooden shelf. Step two: find the source. It was an internet router with a neat row of flashing indicator icons. Every pulse fired in a rhythmic sequence: flash, hold, reset. I squared up directly in front of the fifth tiny LED. When it blinked amber, my own smile glowed in sync. Glitch avoided, full signal confirmed!
